The K&N Air Oil Separator captures blow-by oil in a high-capacity reservoir to protect the engine and intake tract, helping prevent power loss and potential damage. It replaces the factory crankcase line and is engineered for Ford Bronco 2.7L applications for 2021–2022. The unit installs in about 30 minutes with basic tools, uses factory-style hose connections for snap-on service, and is backed by K&N’s No‑Hassle Lifetime Limited Warranty.
