Cummins Engine Intake Manifold Cover

Intake air leaks and boost pressure loss are corrected when the Cummins Engine Intake Manifold Cover is used as a fresh sealing solution for the top end of the engine. This heavy-duty cover plate is designed to handle the high heat and vibration levels produced by ISX and QSX series engines. The machined sealing surface ensures a perfectly flat contact point with the intake gasket to prevent high-pressure air from escaping. Using this genuine Cummins 5474345 replacement prevents the warping and cracking often seen in aftermarket parts that can't handle the constant thermal cycling of a big-bore diesel. It serves as a rugged barrier that keeps the induction system pressurized for maximum turbocharger efficiency.
