The Gates valve cover-to-intake emission control hose for 2009–2020 Chevrolet Express 6.0L V8 links the valve cover to the intake tube to preserve emission control and crankcase ventilation. It helps maintain sealed PCV flow, reducing the chance of vacuum leaks that can cause idle and emissions problems. Fit a replacement hose when the original becomes cracked, porous, or otherwise compromised.
