K&N Drag Racing Air Filters Increase Performance and Airflow
- Jan 14, 2014
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.
