Pre-Filter Black Oval 17 in x 6in x 5in Tall

The Pre-Filter Black Oval 17 in x 6 in x 5 in Tall by Outerwears is an essential intake protection component designed for serious off-road enthusiasts and performance-minded mechanics who demand cleaner air without sacrificing flow dynamics. This pre-filter wraps around your primary air filter element, acting as a first-stage defense against dust, dirt, and debris that would otherwise compromise engine efficiency and filter longevity.

Outerwears engineering delivers a black polyurethane foam construction that balances air permeability with particle trapping efficiency—a proven design principle trusted across racing and high-performance applications. The 17-inch length and oval cross-section (6 inches wide, 5 inches tall) provide significant surface area to reduce clogging intervals while maintaining unrestricted intake velocity. This geometry works effectively with both OEM and aftermarket air box designs, staying securely in place while allowing quick visual inspection without complete disassembly.

The lightweight foam material generates zero parasitic drag on your intake system, meaning your engine sees full boost and uncompromised airflow characteristics. Mechanics and builders installing performance intake systems will appreciate the ease of use and effectiveness of this pre-filter, ensuring optimal performance in various applications.
