Pre Filter Black w/Top 11in Dia x 5in Tall

The Pre Filter Black w/Top by OUTERWEARS is a precision air intake filtration component designed for high-performance engines in tactical vehicles, generators, and off-road platforms where dust ingestion poses a mission-critical threat. With an 11-inch diameter and 5-inch height, this pre-filter serves as the first line of defense against airborne contaminants in austere environments—from desert operations to field deployments where engine longevity directly impacts operational readiness. Law enforcement and military operators rely on quality pre-filtration to extend engine service intervals and maintain reliability under extreme conditions.

This OUTERWEARS pre-filter leverages dual-stage foam construction to capture larger particulate matter before it reaches the primary air filter element, reducing filter load and extending filter life by 40–60 percent in dusty operations. The black foam formulation is engineered to resist UV degradation and maintain structural integrity across temperature swings common in tactical fieldwork. The integrated top cap design simplifies installation and prevents debris bypass, while the compact 4.95 x 1.45 x 6.5-inch envelope fits tight engine bays without requiring extensive modifications. Weighing just 0.06 lbs, it adds negligible mass while delivering measurable reductions in maintenance burden.

This pre-filter is ideal for operators running air-cooled engines or turbocharged platforms in sandy, volcanic, or high-dust terrains where standard filtration alone proves inadequate. Installation is tool-free and reversible—simply position the unit upstream of the primary intake filter and secure with the included retaining ring or clamp hardware. Compatible with OUTERWEARS universal air-intake kits, this black pre-filter integrates seamlessly into existing filter assemblies on pickup trucks, ATVs, portable generators, and military-grade power units. For maximum engine protection during extended field operations, replace every 100 operational hours or when visual inspection reveals saturation.
