The Gates valve-cover-to-intake emission control hose (right side) for 2001–2006 Lexus LS430 V8 4.3L connects the valve cover to the intake to route crankcase gases back into the intake system. Designed as a replacement for the specified LS430 right‑side application, it restores correct PCV/emissions routing and addresses wear-related leaks that can affect idle and emissions.
