 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.

Skip ahead to today, and the widely used Pre-filter can be seen on a variety of applications from circle track racing, street, motor-cross, jet-ski, ATV, snowmobile, kart, military, industrial machinery, and consumer appliances. Outerwears has a product for virtually any air intake application.
