Product Description

The K&N 81-0800 Air Oil Separator protects the engine and intake tract of 2011-2024 Ford F-150 trucks from harmful blowby contamination. Designed for 2.7L EcoBoost, 3.5L EcoBoost, and 5.0L Coyote engines, this catch can captures oil vapors in an industry-leading 6 oz high-capacity reservoir before they can enter the intake system. By preventing oil and contaminant build-up in the intake tract, the separator helps protect against power loss and premature detonation. The aluminum construction with durable black finish provides resilience and a clean appearance. Installation takes approximately 20-30 minutes with basic tools and requires no drilling. Factory-style hose connections snap on and off quickly, while the tool-free reservoir design allows easy checking and emptying without special equipment. Backed by the K&N No-Hassle Lifetime Limited Warranty.
