K&N's air filter that outflows stock, and adds up to 15 hp.
These reusable K&N Filtercharger air filters outflow any other air filter--up to 900 cfm--for power gains of up to 15 hp. They use a surgical cotton fabric soaked in oil as their tack barrier. Sandwiched between an aluminum screen wire, the holes in the cotton catch tumbling air and straighten it out. Since air moving in a straight line flows faster, these K&N air filters actually improve airflow. They can be covered by up to 1/4 in. of debris before air restriction makes cleaning necessary. These K&N air filters come pre-oiled, and many are available as a direct fit for your application. So, if you want better performance from your air filter, then you need to have one of these K&N air filters in your ride.
