K&N Drag Racing Air Filters Increase Performance and Airflow

K&N Drag Racing Air Filter 28-4245
K&N Drag Racing Air Filter 28-4245
K&N has been making air filters for high performance applications since 1969. The oiled cotton gauze air filter design was first developed for off-road racing, where high rates of airflow and excellent filtration efficiency are essential ingredients in the recipe for victory. Another place where K&N air filters really helps to increase performance and protect valuable engines is in drag racing. Drag racing engines develop enormous amounts of horsepower and require exceptionally large amounts of air to do so. With such tight tolerances in these race motors, that air needs flow freely and be clean.
K&N 28-4235 Tapered Drag Racing Air Filter
K&N 28-4235 Tapered Drag Racing Air Filter


Enter, K&N’s drag racing air filters and complete assemblies. These air filters utilize a dry, 2-ply cotton gauze filter media and a large surface area to help minimize restriction and increase airflow to these heavy-breathing motors while still protecting the motor from dust and debris. They’re designed to fit popular hood scoop designs and come in a variety of sizes to fit a wide range of applications. Whether you want to replace an air filter in your current setup, put a filter in your scoop, or install a complete high-performance assembly, K&N has you covered.

The K&N 28-4235 air filter is 6 3/8 inches tall and tapers from 11 inches in diameter at the base to 9 inches at the top. It’s designed for use in popular Formula Atlantic and Super Vee style cars used in racing today and it can fit into many racing air scoops.

If you have a 9 inch outside diameter air filter assembly, you can help your engine to breathe easier by installing the K&N 28-4245 at 3 inches tall, or go big with the 28-4240 air filter at 5 inches tall for even more airflow and performance. You can also replace the lid on your 9 inch assembly with the K&N 66-0900R X-Stream Air Flow Top to pull in more air for even greater performance efficiency.

For a complete assembly with a 5 1/8 inch neck flange carburetor or throttle body, run the K&N 66-3340R Drag Racing Base Mount Scoop Filter. This assembly incorporates the 28-4235 air filter with an X-Stream Air Flow Top for a complete package of improved performance.

Choose the 66-3300R or 66-3310R if you’re running a 7 5/16 inch Dominator-sized carburetor or throttle body and need a tapered filter assembly to fit in your scoop. These two assemblies both use the 28-4235 air filter and an X-Stream Air Flow Top to help increase airflow, performance and efficiency. The 66-3300R incorporates a lower-profile baseplate than the 66-3310R, which helps ease fitment in applications with cramped quarters around the air filter.

For 7 5/16 inch Dominator-sized carburetor or throttle body applications where a tapered filter isn’t necessary, K&N offers the 66-3330R and 66-3320R Drag Racing Base Mount Scoop Filters. Both of these assemblies have a 9 inch outside diameter air filter and X-Stream Air Flow Top, and come with different heights to help fit your needs. The 66-3330R comes with a 3 inch tall filter and the 66-3320R comes with a 5 inch tall filter for even more airflow and performance.

All of these drag racing filters are washable and reusable so they don’t have to be replaced over and over again like disposable paper air filters and are backed by K&N’s One-Year Limited Warranty.

1999-2010 360, 430 and F430 Ferrari Models Improve Performance with K&N Air Filter Upgrade

The soul of the black mare dancing on every Ferrari badge is provoked by a longstanding tradition of Formula One racing domination. Ferrari and winning are synonymous, and what they discover on the track, gets integrated into every car they design, case in point the1999 Ferrari 360. The 360 was called the F131, and the company produced about 10,000 of them.
K&N Replacement Air Filter for Ferrari 430, F430 & 360
K&N Replacement Air Filter for Ferrari 430, F430 & 360


The 360 looked fast and represented bona fide Italian automotive lust, yet chief designer, Frank Stephenson, the director of Ferrari-Maserati design group, felt it was "a little flabby." What evolved next was the F430, capable of accelerating from 0-62 mph in a mere 4.1 seconds and reaching a top speed in excess of 193 mph.

The F430 features a lightweight V8 engine that produces a robust 490 horsepower at 8500 rpm and 343 ft-lbs of torque at 5250 rpm. To fire-up the engine the driver presses a large "Engine Start" button located on the left of the steering wheel, and once engaged, the engine symphony produces an exhaust note that will bring tears of joy to any car enthusiast eyes.

Ferrari and K&N share several essential common threads, both share a tradition of winning and both incorporate what they learn on the track into their street designs. A typical example is the new K&N 33-2494 high-performance, reusable air filter. By simply replacing the existing air filter in any of the models listed below with a K&N 33-2494, you will let your Ferrari breathe better and run better, while at the same time providing excellent engine protection. The two K&N air filters in each box are designed to fit into the existing factory air box without modifications of any kind required.

K&N’s specially pleated, high-flow filter design creates a large surface area, allowing the K&N 33-2494 air filter to continue to perform flawlessly for extended maintenance intervals. Depending on your driving conditions, servicing intervals can reach up to 50,000 miles. When filter maintenance is required, cleaning the air filter is as easy as following the four effortless steps on a K&N Recharger Kit.

The high performance K&N 33-2494 air filter will be the only air filter you’ll ever need to purchase for your Ferrari - K&N backs that promise with their renowned Million Mile Limited Warranty.

K&N 33-2494 fits the following Ferrari F430 & F360 models (Includes 2 filter per box)

Andy Forsberg Recaps His Successful 2013 Season Racing for Three Separate Teams

This is the F&F X1 360 Sprint Forsberg raced for Placerville track points and for the 360 CA Civil War Series.
This is the F&F X1 360 Sprint Forsberg raced for Placerville track points and for the 360 CA Civil War Series.
The one thing every driver and car owner craves is success. Every decision they make is geared towards that single ambition. Success isn't black and white though, like life, it comes in varying shades. Where a top-10 finish may spell triumph for some, others have elevated their personal achievement bar so high that anything less than extraordinary falls short.
Forsberg lists winning the 1st annual Tyler Wolf Memorial in the A&A Motorsports No. 92, 410 Sprint Car as a 2013 season highlight.
Forsberg lists winning the 1st annual Tyler Wolf Memorial in the A&A Motorsports No. 92, 410 Sprint Car as a 2013 season highlight.


The latter category is where K&N's Andy Forsberg finds himself. Over 2011 to 2012 alone, Forsberg has a combined 24 Feature wins, two Placerville Speedway and two Civil War Series Championships, to name just a few highlights. After a 66 race, 2013 season, driving for three different teams, the final tally confirms that Forsberg has now extended his string of extraordinary seasons to three in a row. This year Forsberg raced in the F&F Racing x1, the A&A Motorsports No. 92, and the P.T. Shocks 7c.

We caught up with the tireless Forsberg to get his take on how the year looks in his rearview.

When you look back on 2013, do you compartmentalize your successes by team, or do you weigh the overall season results in one pot. And how does this season stalk up in your opinion?

"I like to break stats down by each team to see where I need to improve. I'm very happy with this season, obviously I would have liked to have been a little more competitive in the F&F X1, but we had set the standards so high from the last two seasons of being so successful. The 2013 season stats for that team were good; we just want and expect to be better, and to outperform each previous year. I'm very competitive, and so is the F&F X1 team, so we constantly strive to be No.1 and get the wins."
"This is my family owned 360 non-wing sprint I race when the other three teams don't want to go racing."
"This is my family owned 360 non-wing sprint I race when the other three teams don't want to go racing."


What would you say brought you the most joy and/or satisfaction this season, and what were some of your biggest disappointments?

"Winning the 1st Annual Tyler Wolf Memorial race in Chico, California at the Silver Dollar Speedway was very special. And then to back that up two weeks later, racing with the World of Outlaws at the 60th Annual Gold Cup Race of Champions, and running 3rd on Friday night, and 2nd on Saturday night was a pretty big deal for a local team with a volunteer crew. My biggest disappointments would definitely be the trip to the hospital in April. That cost me an entire nights worth of points for the Silver Dollar Speedway track championship."

With the F&FX1 team you mention struggling to find speed, consistency and finishes, have you been able to put your finger on why that was?

"There really is not a smoking gun with the X1. We still had a good year, it just wasn't up to the high standards we set in 2011 and 2012. I know I'm not going to be able to just march through every season without any ups and downs, it's part of racing, and this year we had some downs. You just try to keep working hard and get over the hump."
"This is the PT Shocks 7c 360 winged sprint car owned by Cody Gainey that I race at miscellaneous races when the other teams don't want to race."

After a 66 race season are you just happy to relax during the off season, or are you already working on next season plans?

"I wouldn't mind racing all year around. I'm involved with three good teams that could manage that, but I will say that having three months off is kind of nice to be able to re-group a little bit. Mostly I would say it's nice to get my sleep schedule back in order, racing two nights a week, and staying up late those nights, takes a toll on me after a while. During the winter months it's nice to be able to get right up in the morning, instead of pushing snooze three or four times, like I do during racing season."

"Thanks to everyone that has let me drive their cars, to all their pit crews, the fans, K&N and all the sponsors, and to my family and friends. This was a wonderful season, full of good memories, and I could not have been as successful without each and every one of you."

Forsberg's Combined 2013 Stats:
66 races
17 fast times awards
Qualified in top- 3, 32 times
12 main event victories
26 top-3 finishes
38 top-5 finishes
