The Gates valve cover-to-throttle-body emission control hose for 2011–2016 Chevrolet Cruze 1.8L 4-cylinder connects the valve cover to the throttle body to support emission control and crankcase ventilation. It helps maintain sealed PCV routing and can reduce vacuum leaks that affect idle and emissions. Replace a deteriorated or leaking hose to restore correct ventilation and intake sealing.
