Specially designed filter wrap made to extend the service interval of your K&N Filter when used in very dusty conditions.
Made from durable polyester material containing uniform micron openings.
The PreCharger will stop small dirt particles; yet add little restriction to the airflow of the filter.
Designed to be run dry and can be cleaned with K&N Filter Cleaner.
Custom made to fit each application.
Double stitched elastic openings assure that the PreCharger will stay in place.
