INCREASE PERFORMANCE

High-flow cotton media is designed to allow up to 50% more airflow than traditional paper filters—and greater airflow can result in increased horsepower and torque. K&N® air filters are tested on a SuperFlow flow bench to ensure increased airflow over a stock filter. View testing data for many K&N filters on individual product pages.
