The Ford F150, the best-selling American-made pickup truck in recent decades, needs no introduction. It boasts many options and models that its rivals cannot match and the 2012 and 2013 model years continue this dominance with four engines to choose from, three body styles, and nine different trim levels. The base engine in the 2012 and 2013 Ford F150 is a 3.7 liter V6 that pumps out an impressive 302 horsepower and 278 pound-feet of torque while still only sipping fuel with an estimated 23 miles per gallon on the highway.
Even with impressive factory horsepower numbers from the base engine option, 2012 and 2013 Ford F150 3.7 liter owners can gain a simple increase in horsepower and engine performance with the K&N 77-2585KS performance air intake system. The 77-2585KS is precision-engineered with a mandrel-bent aluminum intake tube to streamline airflow and heat shield to help protect incoming air from heat under the hood. The RC-5173 conical air filter on the end of the intake tube is oversized to help reduce restriction while maintaining excellent air filtration. It is also washable and reusable, and can go for up to 100,000 miles between cleanings depending on driving conditions.
On the dyno, the 77-2585KS performance air intake system produced an estimated additional 11.9 horsepower at 5536rpm, and 10.3 pound-feet of torque at 3333rpm over the stock intake system.
The 77-2585KS is backed by K&N’s famous Million Mile Limited Warranty. It’s easy to install, maintains all necessary factory connections, and does not require any additional modifications to the vehicle.
Performance air intake 77-2585KS is engineered to fit the models listed below:
2013 Ford F150 3.7L V6
2012 Ford F150 3.7L V6

Most big truck owners have at one time or another, owned a K&N product or driven in a vehicle with a K&N product. Even though this article doesn’t really deal with lifted trucks, we thought you might be interested to hear about the legacy of the K&N founder.
Every self-respecting, old school motorcycle devotee has a short list of idols indelibly etched onto their recollections, two-wheel pioneers that cleared a trail so the rest of us could see where and how to follow. With their injections of pure cool and expertise, these intrepid individuals stared down the shortsighted conventions of their time and forever changed the nature of motorcycling’s approval rating. Steve McQueen, Malcolm Smith and Norm McDonald sit atop that cerebral list for many.
Norm McDonald has been an ambassador for motorcycling his entire life, as a racer, promoter, teacher, sponsor and advocate for motorcyclists’ rights and safety. Norm is also the “N” in the internationally recognized K&N logo. And, on Friday October 18, during the AMA Motorcycle Hall of Fame Legends Weekend, in a star-studded celebration at Las Vegas’ Green Valley Resort & Casino – Norm will be a member of the elite Class of 2013 officially being inducted into the Hall of Fame.
“Being inducted into the AMA Hall of Fame was a surprise and a shock and I’m extremely honored,” remarked Norm. “I learned of the nomination from a long time friend, John Ulrich of Roadracing World, but I didn’t think it would go any further.”
What Norm didn’t know at the time was that two of his sons, Phil and Pat and Phil’s wife, Cindy, had compiled a thick, comprehensive book about Norm and his accomplishments and sent it to the AMA for consideration. “I was numb and speechless when I first got the news,” he added.
The king of air filters and the icon for motorsport legends the world round, K&N Engineering as it’s known today, flourished from Norm and his humble roots, aided by a simple twist of fate.
“When we first met I was racing a BSA Gold Star and Kenny was the head mechanic at the shop I rode out of. Kenny started helping me on my bike in the evenings, and at the races, and we became very good friends,” recalls Norm. “I worked for a surveyor at the time, and I had designed a carrier for the crews.”
Simplicity is the root of all genius, believed Albert Einstein, and Norm was doing his part to validate that assertion. What Norm had invented was a stake and hatchet carrier for the chainman to carry when they were laying out a road or subdivision. “The K&N lath and stake carrier will save up to 45 minutes per day. Per survey crew,” read the advertisement.
“Kenny said let’s build and market them, so we started building them in my garage every night. The carriers sold well until we went to patent it and the attorney wiped out what little money we had. So we decided to open our own motorcycle shop with about $200 and three used motorcycles. Kenny and I opened K&N Motorcycles in 1957 in Loma Linda, California.”
“Kenny ran the shop and I kept my surveyor job for three years, by then we had moved to downtown Riverside. We were Royal Enfield, BSA dealers and took on Yamaha in 1958. Frank Cooper was the distributor. In the 1960’s we also made high fenders and brackets for Yamaha street enduros and Honda models, and fork braces, handle bars and fairings for roadracers. Then in the late 1960’s and early 1970’s we built SouthWind 21 ft. ski boats with 454 GM motors too, because I had started into racing SouthWind boats. Jim Youngblood owned the company and we bought into it after I started racing for him.”
Ken and Norm moved the shop from Riverside, California to Tulsa, Oklahoma in 1971 and after 55 years they’re still going gangbusters. K&N Motorcycles is today the world’s oldest Yamaha dealership in the country. Norm continued to race motorcycles all through the 1970’s, competing in desert Hare and Hounds, endurance events, scrambles, TT and some flat track.
“I raced modified midgets and mini sprint cars from 1985 until 1995, that’s when I flipped end-over-end and broke both of my hip replacements. That ended my racing,” recounts Norm. “Bob Frazier and I built and sold over 50 race cars during that time, but like I said, all this never seemed like a big deal, it was just my life. But my kids say it is.”
Norm and his wife Lucy have been married for 58 years; they have three sons, one daughter and 22 grand and great grand kids.
“I am very happy and proud to have been able to help my three sons, Phil (AMA National Number Flat Track, Roadracing and three-time winner of the AMA Gold Wrench Roadracing award), Pat (cross country and motocross) and Sam (AMA 250 National Champion in 1982, and second place 250 and Superbike finisher in 1984). My grandson Tyler is also a CMRA Roadracing Champion.”
Norm’s inspiration and influence spread far beyond his family however, over the years he has sponsored hundreds of racers through his shop, with more than 30 of them going on to the national level.
“I’m also very happy and proud to have helped Malcolm Smith, both with racing and getting started in the business. Malcolm came to work for us while he was still in school and when we first bought the shop in 1971. Others were Swede Savage, who rode for us from the time he was 12-years-old, up until Dan Gurney got him in to Indy cars. Mike Kidd rode for us three years and Gary Scott for one year, both went on to become AMA No 1.”
Norm’s list of protégés reads like a who’s who of motorsports stars, he worked with World Champion Barry Briggs for one year on the AMA National short track circuit, and Walker Evans, who went from motorcycle racing to pickups. “Ralph White rode our flat track bikes and roadracers and Freddy Edwards won many races for us throughout the US,” Norm adds. “Donnie Castro rode our flat trackers and TT bikes for one year, and then Yamaha signed him the next year. Randy Cleek was Phil’s team mate for three years, roadracing and flat track racing. We counted up as many as we could remember and it was over 250. Plus, trials rider, motocross, ATV and some car racers.”
“I also worked with other bike builders, back when you had to design and build your equipment, instead of being able to buy everything. Don Vesco, Floyd Emdy, Mel Denison and Red Daily and others. What great times those were.”
In 1992 Norm and his son Phil started the Motorcycle Training Safety Center (MTSC) and the Motorcycle Safety Foundation (MSF) and over 8500 riders have graduated from those programs to date.
“I am still very involved in the CMRA,” says Norm. “I have been on the BOD since 1992, president four times, and I’m still the treasure. We have over 700 roadracers. My son Pat and I have also put on the Oklahoma Gold Rush for 17 years and last year we had over 800 riders.” That event happens annually on November 1-3 and K&N Engineering has been a sponsor for the last four years.
The man is indefatigable, he’s also the most sincerely genuine and unassuming person imaginable. Legends live in rarefied air, and far too often they become victims of their own myth. Norm is not that guy. Not by a long shot. Which is why when he’s asked to speak publicly at schools and clubs, people continue to listen.
“I rode until three years ago and I have to have another hip replacement this year, so I hope I will be able to ride again. I think it is wonderful, and I am very proud K&N Engineering is so very successful,” he reflects, “And that I was part of it ,and they continued to carry the name that me and Kenny started with.”
Since childhood Brian Binkert had a dream: a dream of off-road racing. His dream took flight at 16 years old when he got a 1993 Ford Ranger, which turned into a 10-year project full of upgrades and experiments. Through trial and error Binkert grew to trust and rely on K&N Engineering products.
“The K&N Air Intake Systems I use on my vehicles rock! I instantly noticed a horsepower gain, and would suggest them to anyone,” said Binkert. “Another cool thing is that I installed the K&N Billet Oil Filter, which is such a trick piece of machinery. The best part is that you never have to replace your oil filter again!”
Despite his enjoyment of all things automotive, Binkert followed a slightly different career path than was initially anticipated. He correlated his racing fascination and design skills into a more artistic career. After earning a Bachelor of Science degree in Media Arts, Binkert created his own premier graphic design company, Bink Designs, in San Diego, CA, in 2003. The range of graphic design services includes identity, print design, web development, apparel, and photography. Since its origin Bink Designs has evolved, from winning several photography awards and honors to securing an expanded racing clientele.
Throughout his exciting career journey, Binkert has cherished his partnership with K&N Engineering. “Ryan Fellman of K&N had caught wind of me through social Media and now we are growing our relationship,” said Binkert. For more info, check out BinkDesign.com.

2011 and 2012 GMC Sierra 2500HD and 3500HD and 2011 and 2012 Chevy Silverado 2500HD and 3500HD 6.0 liter gas engines are some of the more powerful available on the market today. Adequate airflow is the key to the performance of these large engines. On the flip side of the coin, every driver knows how important filtration is to a vehicle’s operation and engine longevity. To balance high airflow and high filtration efficiency, K&N has developed the 77-3076KTK performance air intake system for 2011 and 2012 GMC Sierra and Chevy Silverado 2500HD and 3500HD trucks with 6.0 liter engines.
Built for performance and show, the K&N 77-3076KTK High-Flow Performance Air Intake is a free-flowing mandrel-bent aluminum tube induction system designed to fit easily into 2011 and 2012 GMC Sierra and Chevy Silverado 2500 and 3500 6.0 liter models. This air intake system comes with a K&N high flow air filter, a custom designed heat shield and lid to help keep engine heat away and all the necessary components needed for installation. The system has fittings for the crankcase breather hose and a mass air sensor adapter custom designed to perform with the factory’s electronics. On top of utilizing the highest quality, vehicle-specific components, the 77-3076KTK is also backed by K&N’s Million Mile Limited Warranty, giving owners the peace of mind to know that their investment is safe.
K&N air intake systems are a simple bolt-on installation that replaces the vehicle’s stock restrictive factory air filter and air intake setup. The 77-3076KTK is also designed to dramatically reduce intake restriction while it straightens air flow. This allows your vehicle’s engine to inhale a larger amount of air than the OEM air filter assembly. Less restriction means more usable horsepower, torque and acceleration throughout the engine’s RPM range. When dyno tested, the air intake system showed an estimated performance increase of 10 horsepower at 5033rpm and 10 lb-ft of torque at 4736rpm on a 2012 Chevrolet 2500HD pickup with a 6.0 liter V8 engine. The air intake system also allows for an increase in engine sound offering a deeper throatier roar when you step on the gas.
The performance air filter, part RF-1042XD, used on the 77-3076KTK intake is also washable and reusable. Being washable and reusable, the RF-1042XD air filter can go up to100,000 miles depending on driving conditions and it is easily cleaned using the K&N recharger kit meaning you can have more time on the road and less time changing expensive disposable air filters in your garage. The filter is designed with a woven oiled cotton media to ensure excellent filtration efficiency for engine protection.
The 77-3076KTK comes with step-by-step install instructions for easy installation. Including pictures of each component and area of the engine bay as parts get removed and installed. Average installation time runs less than 90 minutes depending on the installer’s skill level.
K&N manufactures many air intakes for Chevy Silverado 2500/3500 and GMC Sierra 2500/3500 trucks. See the Chevy Silverado 2500HD, the Chevy Silverado 3500HD, the GMC 2500 and GMC 3500 Truck Air Intake pages on KNFilters.com for details.
Being regarded highly as a top light duty truck manufacturer, Ford has brought new life to the market by offering one of the widest selections of high performing models on the 1/2 ton market. This includes the 6.2 liter option of 2011 and 2012 Ford F150 trucks. Packing a punch with its impressive tow capabilities and throttle response, the 6.2 liter models offer power to drivers looking for a strong 1/2 ton. A near 7 second 0-60 time just wasn’t good enough for the team at K&N, so they designed the 63-2584 Aircharger performance air intake system.
The 63-2584 air intake is an easy to install, bolt-on system, designed to replace the restrictive factory air box and filter. Engineered with a custom rotomolded polyethylene intake tube, large conical cotton air filter (part number RC-5173), and a powder coated heat shield, designed to insulate the filter from ambient engine heat, the 63-2584 offers a number of special features that can improve engine performance and provide excellent filtration. When dyno tested, the 63-2584 air intake boosted performance by an estimated 27 horsepower at 5347rpm and 16.9 lbft torque at 3578rpm. More horsepower and torque are never something to go amiss, especially when under heavy load.
The included RC-5173 washable and reusable air filter offers excellent filtration and engine protection. It can be used for up to 100,000 miles before cleaning is needed, depending on your driving conditions.
The 63-2584 air intake system is also backed with K&N’s world famous million mile limited warranty giving you peace of mind. Serving as a perfect upgrade and way to improve engine performance and throttle response, the 63-2584 air intake from K&N is guaranteed to increase horsepower.

This intake will cost you around $275 – $350 depending on where you purchase it.
As the 2012 SEMA show came to a close recently in Las Vegas Nevada, nearly all the attendees were treated to seeing some of the most amazing vehicles, products and services that the aftermarket industry has to offer. One company with an abundance of new products and custom vehicles in the booth was K&N Engineering. The K&N booth this year was a showcase of new products including air filters, intake kits and parts for nearly any engine. K&N staff were equally pleased to be present teaching customers about what the company had to offer for the new year.
“I feel like a kid in a candy store,” reported K&N product specialist Daniel Shoemaker. “This is my first time at the SEMA show and being here with K&N is a great experience. I am very honored to work with our customers, and help them with creating new business strategies of how K&N could help grow their business,” reported Daniel. “That, and the amount of new products, cars and excitement everywhere for the whole week is great to finally witness in person.”
With two custom motorcycles, a ZR1 racecar and a completely redesigned ZL1, K&N had plenty of horsepower to brag about in their booth before even getting to the new performance intake systems. SoCalTrucks was a little disappointed to see K&N’s booth without a lifted truck. Yeah, motorcycles are cool and muscle cars are okay, but there’s nothing like a huge truck. Especially since K&N was known for a long time as the gold standard in big truck intakes.
Many visitors were also interested in viewing the large air flow demonstrator in the booth which simulated airflow performance of K&N air filters amongst other types of filter media on the market.
“K&N’s presence at SEMA was excellent this year,” said K&N’s director of sales Tim Stewart. “SEMA enables us to connect with many customers and dealers that are located around the world.” Tim Stewart went on to say that he was excited to see many of the visitors stopping by the booth taking note of the new products on display. “K&N works hard to keep up with market demands for new and better products for their vehicles. Whether those products are oil filters, air filters or intake kits, you can expect K&N to be a leader in performance and application coverage.”
With such a strong showing, K&N is sure to excite with more innovative and high quality performance products for the upcoming year.
The Ram 3500 and Ram 2500 are two standouts in the utility and pickup truck world. They have been used in many utility positions where power, reliability, and cargo capacity are necessary. At the heart of these workhorses is the Cummins turbo-diesel engine, which provides excellent towing capacity along with 350 horsepower and 650 lb-ft of torque at the crank.
This kind of performance is excellent but that doesn’t mean there isn’t room for improvement. This is where the K&N 63-1562 performance air intake system comes in. It is designed to open the air intake pathways of Ram diesel trucks and allow them to breathe more easily. This leads to better horsepower and torque and an engine that roars.
The 63-1562 intake system improves performance by an estimated additional 8.2 horsepower and 14.76 lb-ft of torque to the wheels in tests on a 2011 Dodge Ram 2500 with 6.7 liter engine at 2919 RMP. The oversized K&N air filter on the air intake is washable and reusable. It has 6 layers of oiled cotton gauze for the outstanding filtration a diesel engine needs. The filter is covered and protected by an enclosed airbox and snorkel for bringing in lower outside air temperatures. Since this era of Ram can have two different bumpers depending on year and model the scoop includes a 1.5” section that can be cut out so that the snorkel will align properly with either bumper.
The 63-1562 air intake system comes with instructions and all of the hardware necessary for installation. The instructions have pictures and detailed steps making installation simple and straightforward. Additionally this air intake is covered by K&N’s Million Mile Limited Warranty.
K&N has been creating air filters for more than 40 years. K&N air intake systems still follow the same basic idea. If clean filtered air flows more easily into the engine, the engine will make more power to the wheels. With meticulous detail-oriented design, constant testing and the history to back it up, K&N air intake systems deliver power with confidence and reliability.
The 63-1562 air intake system fits the following Ram diesel pickup trucks:
2012 Dodge Ram 3500 Pickup 6.7L L6 Diesel
2012 Dodge Ram 2500 Pickup 6.7L L6 Diesel
2011 Dodge Ram 3500 Pickup 6.7L L6 Diesel
2011 Dodge Ram 2500 Pickup 6.7L L6 Diesel
2010 Dodge Ram 3500 Pickup 6.7L L6 Diesel
2010 Dodge Ram 2500 Pickup 6.7L L6 Diesel
Off-road race vehicles have to deal with lots of dirt and hot air. So optimizing filtration and grabbing cold air to make more power are essential for a team like Off Track Motorsports, that’s run by John Mathews at Auburn Car Repair and Off Road. Mathews wanted a performance intake system for the FJ cruiser he drives in the Sportsman 1800 class, and Volant suggested he try the company’s air intake, equipped with the PowerCore filter. “We won two Bonneville Off-road Racing Association events last year, (Wendover 300 and Jackpot 250),” says Mathews. We then DNF’d at Vegas to Reno after a failed throwout bearing/clutch took us out around race mile 350.”
Mathews, teamed up with Volant after meeting them a vendor show and found out how the air intake and PowerCore filter works. The team was offered a system to try out and Mathews liked how it worked out. “We have had very good luck running the filters, and have had no engine issues or even really plugged a filter up,” says Mathews. “We ran V2R last year and changed the filter halfway through. I believe we ran one filter each for the prior 300 and 250 mile races. They would probably have lasted longer, but in all honesty, in this type of racing, we don’t leave that type of stuff to chance. We like to start each race with a fresh filter.
Along with team partner, David Zartman at 4WD Toyota Owner Magazine, Mathews uses their sponsorship and promotion of Volant to sell his customers on the products. “We do lots of diesel performance stuff in my shop, and the Volant is normally my first recommendation, strictly based on my personal experience with the filters,” He says. “I’m not a fan of the K&N filters, and simply explaining the differences between the styles of filters to my customers and my recommendation, is normally enough to sell my customers on the product.”
You can follow Mathews and his FJ Cruiser racing team on their Facebook page, www.facebook.com/offtrackmotorsports, as they prepare for the next Best In The Desert (BITD) race from Vegas to Reno. For more information on Volant Cool Air Intakes, visit www.volant.com.

Toyota’s path into truck prominence has been direct and straightforward. They entered the U.S. light truck market in 1964 with their introduction of the Toyota Stout, which was marketed until 1969, when it was succeeded by the smaller Hilux. Between 1964 and 1999, Toyota steadily built its reputation for truck quality on a solid line of little pickups. Beginning in 1976, these resilient vehicles were simply called compact pickups. The badge Tacoma wasn’t attached until 1995 and back then its mission was to continue in the tread marks of their legendary line of popular light trucks. It was their sixth generation of Toyota trucks.
The early Tacoma was offered in both 2-wheel and 4-wheel drive models with two body styles: regular cab and Xtracab. Then in 2005 the Tacoma was redesigned and reclassified to a mid-size. The second-generation Tacoma immediately shot to the head of the class, becoming Motor Trend Magazine’s Truck of the Year for 2005.
For 2012, the Tacoma gets yet another moderate refresh, with new looks and even more high-tech features, like Toyota’s Entune voice-command infotainment system. The 2012 base engine is a 2.7 liter, 4-cylinder engine producing 159 horsepower, which offers some rather notable mpg stats with 19 city and 24 highway. The Tacoma has always been considered one of the more nimble trucks for daily chores and commuting, or as worthy off-road contender for weekend warriors.
If you’re looking to add a bit more performance to your Tacoma truck, K&N has a solution for the entire lineup of Toyota Tacoma’s.
K&N can bump up your truck’s performance with several amazingly easy options. The easiest of these is by simply upgrading the existing air filter with one of K&N’s Toyota Tacoma performance air filters. K&N is the inventor of the high flow performance cotton air filter. These filters are made from a special woven cotton material that improves air flow while also providing excellent filtration. The special cotton fabric is completely washable and reusable, and can go up to 50,000 miles before cleaning is needed depending on driving conditions. This air filter should outlast the life of your Toyota truck – K&N just about gives you their word on it with their 1,000,000 mile limited warranty. Plus, installing the K&N air filter is exactly the same as replacing the factory installed filter, with absolutely no modifications required.
For serious power and torque performance benefits, look no further than K&N’s Toyota Tacoma performance air intakes. K&N offers a complete line of air intakes and cold air intakes for most Toyota Tacoma trucks. K&N produces these air intakes custom made for each pickup model to gain power you can feel. Some have a black heat resistent non-metallic tube and some have great looking aluminum tubes with a chrome like finish. K&N’s exceptional intake designs are engineered to lower the air restriction that the factory installed air box produces, which will deliver a guaranteed power improvement for your Toyota Tacoma, while also providing outstanding air filtration.
All K&N air intakes come with a washable and reusable cotton gauze filter element. These filters can be used for up to 100,000 miles before cleaning is needed depending on driving conditions. K&N air intakes are also easy to install and usually only take about 90 minutes from start to finish. Estimated horsepower increases are based on dyno testing. See the K&N website for estimated horsepower gains.
K&N also offers Performance Gold oil filters, Pro Series oil filters and washable, reusable oil filters by Pure Power. Toyota Tacoma oil filters from K&N provide exceptional levels of protection against harmful contaminants and nasty debris that can damage engines, while at the same time, they provide high oil flow rates. K&N Wrench-Off oil filters for the Tacoma are made with a one inch nut welded to the top of the canister for easy removal. Toyota Tacoma Pro Series oil filters from K&N offer great protection and performance at a low cost. K&N’s reusable oil filter by Pure Power provides a housing, bypass valve and call plate that are all CNC machined from Billet 6061 T6 aluminum, so under normal operating conditions, they are also built to outlast the life of your truck.
