K&N Airforce Foam Pre-Cleaner® Air Filter Wraps

K&N Airforce Foam Air Filter Wraps

What is a K&N Airforce Air Filter Wrap?

The K&N Airforce Pre-Cleaner® is a specially designed foam air filter wrap made to extend the service interval of your K&N Filtercharger when used in very dusty conditions.

Red colored pre-cleaner filter wraps are made from large, open cell foam that is oiled. They will stop 90% of the dirt, yet only add a 2% restriction to the airflow of the filter. Our red colored Airforce Pre-Cleaners are designed to be cleaned with K&N Cleaner or soap and water then re-oiled with K&N air filter oil. These pre-cleaners are custom made to fit each application, and there are four universal cut-to-fit sizes available.

Gray colored pre-cleaners are made with smaller foam cells that do not use oil. They are designed to be cleaned with K&N Air Filter Cleaner or soap and water.
