K&N 25-3900 PreCleaner Air Filter Wrap 48 in. x 7 in.

K&N designed this 25-3900 PreCleaner Foam Filter Wrap to extend the service interval of your K&N air filter when used in very dusty conditions. The large open cell foam construction stops 90% of dirt with very low air restriction. This Airforce Pre-Cleaner is designed to be cleaned with K&N Cleaner or soap & water.

Note: Red colored Airforce pre-cleaners are oiled with K&N air filter oil after they are cleaned, and are made from large, open cell foam. Gray colored Airforce pre-cleaners do not use oil, and have smaller foam cells.
