Rainy commutes can wreak real havoc on your engine’s performance. Drizzly downpours drench your vulnerable air filter, clogging the filtration and bringing air flow to a grinding halt. Shield your high-flow air filter from this crippling fate with AFE's Pre-Filter. It slips right over your AFE Air Filter to block water, mud and sand from choking the fast flow of oxygen.

There’s no black magic at work inside your AFE Pre-Filter—just ingenious engineering. The keen minds at AFE cooked up a proprietary hydrophobic process that makes water bounce right off the Pre-Filter’s durable polyester fabric. Then, precision-patterned micron openings close the door on microscopic crud .005” or larger.

Best of all, the AFE Pre-Filter does not get in the way of performance. Cold air still flows freely through the Pre-Filter, through your cotton-gauze air filter and into your motor.
