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 engine damage. This vehicle-specific unit replaces the factory crankcase line and fits Toyota Tundra 3.5L applications for 2022–2023. Install takes about 30 minutes with basic tools; the reservoir snaps on and off for tool-free checks and is covered by K&N’s No‑Hassle Lifetime Limited Warranty.
