If your check engine light is on or you're noticing rough idle on your Chrysler, Dodge, Jeep, or Ram vehicle, a faulty PCV (Positive Crankcase Ventilation) valve might be the culprit. This LYNSHINE part is a direct replacement for OEM number 53032940AB (also known as EMH918). It fits a wide range of models from 2010 up to 2023, including the Chrysler 300, Dodge Challenger/Charger/Durango/Ram, Jeep Grand Cherokee/Wagoneer, and Ram trucks from 1500 to 5500 series, with various engine sizes (3.6L Hemi, 5.7L, etc. – check compatibility for your specific model). The package includes the valve itself plus two replacement gaskets. Replacing this small but important part can help restore proper engine ventilation, reduce oil consumption, and improve performance. Includes a 1-year warranty from LYNSHINE.
