Product Description
MAHLE G32749 intake manifold / grid-heater gasket restores a positive, leak-free seal between the intake horn (elbow), grid heater, and manifold on 1989–2007 5.9L Cummins. Built to OE standards with graphite sealing material, it helps recover lost boost, cold-start performance, and throttle response on stock and tuned trucks alike.
