The K&N Air Oil Separator protects the engine and intake tract by capturing blow-by oil in a high-capacity reservoir, helping reduce power loss and possible engine damage. Designed to replace the factory crankcase line, this unit fits Ford Explorer 3.0L EcoBoost (2020–2021) and mounts conveniently in the engine bay. Installation takes about 30 minutes with basic tools, uses factory-style hose connections, and includes K&N’s No‑Hassle Lifetime Limited Warranty.
