The K&N NASA American Iron Ford Mustang RTR race car was built in-house by the K&N crew and is wrapped in bold K&N graphics

The National Auto Sport Association, or NASA for short, is the sanctioning body behind the American Iron Racing Series. American Iron Racing was created for U.S. made muscle cars such as the Ford Mustang, Chevrolet Camaro, and the Pontiac Firebird. It is composed of three classes, the Camaro Mustang Challenge (CMC), American Iron (AI), and American Iron Extreme (AIX). The classes vary from the CMC, which is composed of nearly showroom stock cars, all the way to AIX, which is almost an open class.

K&N partnered with quality manufacturers like Ford Racing, Optima Batteries, Eibach Springs and Bassani Exhaust to make this dream car a reality

The American Iron (AI), class is situated between the other two, with rules in place for minimum weights and maximum horsepower to weight ratios. K&N Performance Filters specifically built the 2014 Ford Racing Mustang RTR to compete in the AI class. American Iron Racing rules specify that eligible cars must use an OEM frame and chassis or “Body in White” type vehicle shell.

K&N designed a custom ram air induction system for the Mustang using a K&N performance air filter and had it produced it with a form of 3D printing

A 2010 Ford Mustang Body In White (BIW) shell forms the basis of the K&N Motorsports Ford Racing Mustang RTR. At the heart of this American Made pony car sits a stock Ford 5.0L TI-VCT Coyote engine. Power output is tuned to comply with the American Iron Racing horsepower-to-weight ratio rules. According to Dave Martis, R&D Manager at K&N, “The car makes 387 horsepower and 391ft-lb of torque to the rear wheels.”

This Ford Racing Mustang RTR uses two K&N Billet Aluminum Fuel Filters as well as an Optima Redtop Battery

It takes more than an engine and shell to build a racecar. The K&N Mustang RTR uses suspension components from venerable manufacturers such as Cortex Racing, JRi Shocks, and Eibach springs. Stopping power is provided by Baer Brake Systems six piston calipers, 14-inch floating race rotors, and Hawk Brakes racing brake pads. Tires come from Toyo Tire and are the only tires permitted in the American Iron class. The build sheet for the K&N Motorsports Mustang is quite extensive and a full list can be downloaded here.

A CV Products remote oil filter adaptor is used to relocate K&N Wrench-Off Oil Filter number HP-1018 on the Ford Racing Mustang RTR

Of course no K&N built race car would be complete without the world-class filtration products that K&N is famous for. A one-off custom made ram air induction forces cold air through high-flow air filter, number 33-2058, and into the intake system. 33-2058 is an OE replacement style air filter originally intended for Dodge Ram pickups equipped with the 8.0-liter V10 engine traditionally used in the Dodge Viper. Making sure the Coyote motor has clean oil is K&N Wrench-Off Oil Filter, number HP-1018. The higher flow rates, thicker canister walls, and outstanding filtration offered by a K&N Wrench-Off Oil Filter are crucial for race vehicles. In addition to the customary K&N filtration products, this Mustang also uses two K&N Billet Aluminum inline fuel filters. K&N part number 81-1003 is used in the trunk to filter gasoline as it leaves the Fuel Safe fuel cell. Under the hood is billet fuel filter 81-1001 to make sure the fuel is clean before it enters the fuel injection system.

Ryan Walton practiced at Willow Springs and will be heading to Mazda Raceway Laguna Seca for the next AI race

The K&N Motorsports Mustang has performed well since the build was completed earlier this year. Most recently, the car was piloted by Ryan Walton to a second and third place finish at Spring Mountain Motorsports Park in Pahrump, Nevada. Further testing and practice was held this past Friday at Willow Springs International Raceway. Walton and the K&N crew will use a NASA event, not part of the American Iron Racing Series, to further hone skills and perfect the car before heading up to the legendary Mazda Raceway Laguna Seca near Monterey, California. Just two rounds remain in the American Iron Racing Series 2014 season and the K&N Motorsports crew has high expectations.

Upcoming American Iron Races include:
July 26-27: Mazda Raceway Laguna Seca
Oct 4-5: Buttonwillow

Kyle Larson proves he can turn the number 42 Clorox Chevrolet right during the Carneros 200 NASCAR K&N Pro Series West race at Sonoma Raceway

It didn’t take long for Kyle Larson to find his comfort zone again on the NASCAR K&N Pro Series.

Kyle Larson had the fast qualifying time in the Clorox Chevrolet and led every lap of the Carneros 200 NASCAR K&N Pro Series West race at Sonoma Raceway

He won the K&N Pro Series West race at Sonoma Raceway, leading every lap and starting from the pole. He was making his first start in more than a year on the K&N Pro Series. He was a regular on the K&N Pro Series East before making the move to the Nationwide and Sprint Cup Series.

“It’s always fun racing the K&N cars,” Larson said. “I miss running them. I got to run the East Series a couple years ago and had a blast with that. I was really excited about coming here and running the West Series at home.”

It was his first win in the K&N Pro Series West. He won two races and the championship in the K&N Pro Series East in 2012. Winning at Sonoma Raceway wasn’t as easy as it looked though, Larson said after the race.

Coming in second was the leader of the NASCAR K&N Pro Series West standings Greg Pursley, followed by number two in points, Dylan Lupton in his Sunrise Ford of Fontana race car

“It seemed like they would always stay with me on a restart until I got to turn 7,” Larson said. “I was able to gap them a little bit there. I just struggled with choosing the right lines in the beginning of the race.”

Larson, from Elk Grove, Calif., is a rookie on the NASCAR Sprint Cup Series. After winning the Carneros 200 at Sonoma Raceway, the driver for Chip Ganassi Racing qualified third for the Sprint Cup Series race.

“I thought I would be OK when I came here,” Larson said. “I didn’t think I would be that good. I still don’t really think I’m that good. We just qualified good. Looking back, I was a little bit frustrated after the qualifying run. I gave up a lot of time I thought out on the track, could’ve had a shot at the pole.”

A representative from K&N Performance Air filters was on site to congratulate Kyle Larson on his win in the Carneros 200 NASCAR K&N Pro Series West race at Sonoma Raceway

Larson wasn’t the only Sprint Cup Series driver in the K&N Pro Series West field. Ricky Stenhouse Jr., who drives for Roush Fenway Racing in the Sprint Cup Series, was fourth in the K&N Pro Series West race.

Justin Allgaier, also a Sprint Cup Series regular, was 14th in the K&N Pro Series West race.

Greg Pursley, who leads the K&N Pro Series West standings, was second in the race at Sonoma. He increased his lead to 21 points over Dylan Lupton, was who third in the race.

The race ended with a green-white-checkered flag finish. There were five caution periods for 16 laps in the race.

“We had a top five car,” Lupton said. “I just knew I had to get a little bit of a gap on him to hold them off. Luckily I was able to do that on the green-white-checker. That first lap, I was able to get about a 20-car gap on Stenhouse behind me. That just opened me up to cruise to a third-place finish. Larson and Pursley were very fast all day long. It was hard to keep up with them.

Pursley has six top-five finishes in six K&N Pro Series races this year. He won the K&N Pro Series West Race at Kern County Raceway Park in California on May 24.

“Happy to come home second today,” Pursley said. “I think that’s our best finish here. Got another top five and that’s a good day for the points.”

Brandon McReynolds rounded out the top five with a fifth-place finish.

The next race on the K&N Pro Series West is the Stateline Speedway in Idaho on July 12. 2

Geico Motorcycle EnduroCross races begin with riders lining up behind a gate, just as they do in Supercross

EnduroCross is a form of motorcycle racing that blends some of the most exciting elements of motorcycle competition from Supercross, Trials, and Enduro racing. Endurocross racing is typically held indoors in an arena where fans can see all the thrills and spills. An EnduroCross course incorporates multiple elements found in off-road riding such as jumps, rocks, boulders, logs, sand, mud, a water hole and anything else the course designer wants to throw at competitors. It has been described as the “toughest racing on two wheels”. EnduroCross is an exciting spectator sport and was added to the X Games in 2011.

To get around the course quickly AMA EnduroCross fueled by Monster Energy racers turn logs into a series of jumps

K&N Performance Filters has partnered with AMA Geico Motorcycle EnduroCross fueled by Monster Energy as the official Air Filter and Oil Filter for the 2014 season. John Jump, Powersports Brand Manager for K&N, said this partnership exists because “We have watched the EnduroCross series grow over the years and thoroughly enjoy each of the events, the obstacles, and the excitement it creates for the fans.” Jump continued to say “K&N Filters are a great fit for EnduroCross racers and fans alike. We look forward to bringing awareness of our full line of products during the 2014 series.”

Rocks and boulders are difficult even for professional Geico Motorcycle EnduroCross competitors

Lance Bryson, Director of Marketing and Sales for EnduroCross is quoted as saying “K&N has a great legacy in all forms of motorsports so we are extremely proud to have them join the EnduroCross family for 2014.” Bryson went on to say “The Geico EnduroCross Series is all about quick acceleration, short bursts of power, and unwavering throttle response. With K&N High-Flow Air Filters, off-road riders can expect all of that.”

The 2014 Geico Motorcycle EnduroCross fueled by Monster Energy season travels the U.S. beginning in Las Vegas, Nevada and ending in Ontario, California. The full schedule of events is listed below. Ticket information can be found on the EnduroCross website. If EnduroCross isn’t heading to your area in 2014, check with your TV service provider to find show times.

More horsepower and torque for second generation Dodge Charger, Challenger, and Chrysler 300 with a Hemi V8 engine

The Chrysler LX platform based 300, Dodge Charger, Challenger and Magnum could be considered a U-turn in new car engineering when it was released in 2005. Auto manufacturers had shifted nearly all their cars to front wheel drive and very few offered V8 engine options. Chrysler and Dodge made a bold, but successful move, when their engineers used many Mercedes-Benz components in their design. Sadly the Dodge Magnum has been discontinued; yet the Chrysler 300, Dodge Charger, and Dodge Challenger live on and are now in their second generation of production.

Stop searching for cold air intakes, Performance Air Intake System 63-1114 from K&N Filters is here for second generation Dodge Charger, Challenger, and Chrysler 300 with a Hemi V8 engine

While a 5.7 liter Hemi V8 engine commands respect in stock trim, many owners are searching for a Chrysler 300, Dodge Challenger or Dodge Charger cold air intake to increase power. If you’re that owner, look no further than K&N’s 63-1114 Performance Air Intake System. The 63-1114 is expert-engineered and guaranteed to increase horsepower and torque. It replaces the restrictive factory system with a free-flowing, high-density polyethylene air intake tube to help minimize restriction, straighten, and increase airflow to the engine. More air means more usable power throughout the engine’s RPM range.

Dyno Chart - 2011 Dodge Charger 5.7 liter Hemi V8 gains an estimated 11.7 horsepower

K&N’s RF-1042 conical performance air filter is fitted to the inlet of the K&N K&N 63-1114 Performance Air Intake System to provide excellent airflow rates as well as outstanding filtration efficiency. The filter is washable and reusable and can go up to 100,000 miles between cleanings, depending on driving conditions. Additionally, 63-1114 incorporates a heat shield which helps to direct relatively cold air entering through the factory inlet into the K&N Performance Air Filter, number RF-1042.

2012 Chrysler 300 LX Platform with 5.7 liter Hemi V8 Engine

The K&N 63-1114 Performance Air Intake System produces notable horsepower and torque increases worthy of the mighty 5.7 liter Hemi V8 engine. On the dyno, when installed on a 2011 Dodge Charger 5.7 liter Hemi V8, the K&N 63-1114 Performance Air Intake System produced an estimated additional 11.77 horsepower at 4513 rpm and 14.45 pound-feet of torque at 4494 rpm. Similar results can be expected for Chrysler 300 and Dodge Challenger 5.7 liter Hemi V8 equipped models.

The 63-1114 performance air intake system is an easy to install performance upgrade that can be installed in about 90 minutes or less using basic hand tools, and by following K&N’s simple step-by-step instructions. It maintains all necessary factory connections and does not require any additional modifications be made to the vehicle. K&N backs the 63-1114 with the famous K&N Million Mile Limited Warranty so owners can rest assured that their intake system can stand up to tough conditions.

Performance Air Intake System 63-1114 is guaranteed to increase horsepower and torque on the Chrysler and Dodge models listed below:
