Product Description

These reusable K&N Filtercharger air filters outflow any other 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, the filter actually improves airflow. They can be covered by up to 1/4 in. of debris before air restriction makes cleaning necessary. The filters come pre-oiled, and many are available as a direct fit for your application.

Customer Reviews

Great air filter.
I was skeptical at first with this air filter which was a greater cost than other filters. After installing it, I feel the engine gives out a bit more power. You can definitely feel the difference in the engine. Plus it is reusable.

KN Air Filter for my G35
I have noticed a little more power in the mid to high power range. Although I haven't seen an increase in gas mileage. It's to soon to judge the overall reliability and performance, but I am satisfied so far!
