Designed to Increase Horsepower with up to 50% More Airflow

K&N automotive OE (original equipment) replacement air filters generally add 1 to 4 horsepower, due to the unique characteristics of our filter media. K&N air filter media was originally developed for desert motocross racing. K&N air filters were created for an environment that required maximum horsepower and acceleration while protecting the engine from the dirt and dust of off-road racing.

Washable High-Flow K&N washable and reusable air filters are handmade in the USA using only the finest materials. It is almost impossible to wash your K&N air filter or air cleaner too much. K&N washed and re-oiled one K&N air filter more than 100 times, inside our testing laboratory, and it still performs up to specification. K&N air filters can go up to 50,000 miles between cleaning, depending on your driving conditions.
