The Gates emission control hose for 2011–2013 Chrysler 300 V6 3.6L connects the valve cover to the air cleaner as part of the emissions system. It replaces the original valve-cover-to-air-cleaner hose, keeping the intended routing between the crankcase/PCV area and the intake to preserve the vehicle's designed emissions control flow path.
