The Gates valve cover-to-intake emission control hose for 2017–2024 Nissan Pathfinder 3.5L V6 links the valve cover to the intake tube to support emission control and crankcase ventilation. It restores sealed routing for PCV flow, helping prevent vacuum leaks and drivability issues tied to degraded hoses. Install a new hose if the original shows cracks, leaks, or brittleness to maintain proper emission plumbing.
