Outerwears Pre-Filter Black 7-1/4 W x 17-3/4 L x 4-3/8in H

Founded over 36 years ago, Outerwears was created to fulfill a desperate need to keep the Air filter and engine clean during off road racing.

Racers and engine builders were experiencing loss of horsepower and engine damage due to sand, dirt, and other debris prematurely packing (clogging) the filter and often passing through the filter into the engine. Filters loading up with dirt meant loss of horsepower and in many cases loss of a race. Race crews were noticing severe engine damage due to dirt entering into the engine. Thus, a true need for a product designed to keep out additional dirt without interfering with airflow was necessary.
