K&N Universal Airforce PreCleaner Black Air Filter Foam Wrap 16in D x 5in H - 25-5400

K&N Airforce precleaners are specially designed foam filter wraps made to extend the service interval of your K&N Filtercharger. Made from large open-cell foam, the Airforce precleaners will stop 90 percent of the dirt, yet add only a 2 percent restriction to the airflow of the filter. These wraps are designed to be used with K&N filter oil and must be cleaned with K&N cleaner or soap and water. The Airforce precleaners are custom-made to fit different applications, and there is a universal precleaner with Velcro® attachments.
