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.

  • High air flow with excellent filtration
  • Designed to increase horsepower and acceleration
  • Fits into existing factory air box, no cutting or fitting is required
  • Filters are washable and reusable and are backed by K&N's million-mile limited warranty

    There's not much to go wrong here... nothing mechanical... just a good quality filter. The price was below anything else I could find on the web, and as I bought two, free shipping. ...more info
