What is a K&N Airforce Pre-Cleaner?
The K&N Airforce Pre-Cleaner is a specially designed foam filter wrap made to extend the service interval of your K&N Filtercharger when used in very dusty conditions. They are made from large, open cell foam. The Airforce Pre-Cleaner will stop 90% of the dirt, yet only add a 2% restriction to the airflow of the filter. The Airforce Pre-Cleaner is designed to be used with K&N Filter Oil and must be cleaned with K&N Cleaner or soap & water. The Airforce Pre-Cleaner is custom made to fit each application, and there are four universal cut-to-fit sizes available. |
