Breather Filters & Pre-Filters

Protect your engine from harsh environmental elements, optimize crankcase ventilation, and extend the lifespan of your main intake filter with performance breather filters and pre-filters. High-performance and forced-induction engines naturally generate excess crankcase pressure and oil vapor (blow-by). Routing these gases back into your intake manifold coats your intercooler, intake tract, and intake valves in power-robbing oil sludge. Upgrading to clamp-on or push-in engine breather filters allows your valve covers, crankcase, or catch can setup to vent cleanly to the atmosphere, keeping your intake tract spotless and preventing detonation.

For vehicles operating in extreme environments—such as off-road trucks, overland rigs, and track cars—an intake pre-filter is essential cheap insurance. These specially designed hydrophobic (water-repellent) mesh filter wraps slip directly over your primary open-element cone filter. They deflect splashing water, heavy mud, and coarse dust particles before they can pack into the filter pleats, significantly reducing maintenance intervals while preventing catastrophic hydro-locking. Explore a wide selection of washable valve cover breathers, crankcase vent filters, and micro-mesh water-resistant filter wraps sized to fit virtually any aftermarket intake configuration.
