Protect your engine from harmful oil blow-by with the K&N 81-0804 Performance Air Oil Separator. Designed specifically for GM trucks and SUVs equipped with the 5.3L or 6.2L V8 engine, this direct-fit oil catch can captures oil vapors before they can enter the intake system, helping keep the throttle body, intake manifold, and combustion chambers cleaner for consistent performance. By reducing oil contamination in the intake tract, it helps protect against carbon buildup, power loss, and premature detonation.
The K&N Air Oil Separator features a large 6-ounce aluminum reservoir that efficiently separates oil from crankcase vapors while allowing clean air to return to the intake system. Premium OEM-style quick-connect fittings and durable molded hoses provide a factory-quality installation with no cutting or permanent modifications required. The reservoir can be inspected and emptied without tools, making routine maintenance quick and convenient.
Engineered as a vehicle-specific direct-fit kit, the 81-0804 installs in approximately 30 minutes using basic hand tools. Backed by K&N's No-Hassle Lifetime Limited Warranty, it's an excellent upgrade for both daily-driven and performance-oriented GM trucks and SUVs.
