Intake Manifold Gasket Set Cummins 6.7L 09-Up

The Intake Manifold Gasket Set Cummins 6.7L 09-Up by COMETIC GASKETS is engineered for diesel truck owners and mechanics who demand reliable sealing performance on modern Cummins powerplants. This gasket set addresses a critical junction where the intake manifold meets the cylinder head—a high-temperature, high-pressure zone prone to failure in aging engines or those running elevated boost levels. Whether you're rebuilding after 150,000 miles or fortifying an engine for performance tuning, a quality intake manifold gasket set prevents vacuum leaks, coolant seepage, and combustion gas bypass that rob power and trigger check-engine codes.

COMETIC's reputation in the automotive gasket industry stems from precision manufacturing and material science—this set is engineered specifically for the 6.7L Cummins architecture introduced in 2009 and carried forward across Ram HD, Ford, and Dodge platforms. The gasket composition is optimized to withstand sustained EGT (exhaust gas temperature) exposure, oil exposure, and the thermal cycling inherent to diesel combustion. Unlike OEM gaskets that degrade over time, aftermarket COMETIC units maintain consistent compression and sealing integrity across multiple heat cycles, making them ideal for both street and light-duty performance applications where consistency matters.

This gasket set is essential for any owner undertaking upper-end work on 6.7L Cummins engines from 2009 onwards, including manifold removal, turbo replacement, or EGR system service. Installation requires standard mechanical skill and basic hand tools; most technicians complete the job in 2–4 hours depending on ancillary work. Pair this set with fresh fasteners and a torque wrench set to factory spec for optimal results. Mechanics and enthusiasts trust COMETIC for critical sealing applications where leak-free performance directly impacts engine longevity and diagnostic trouble-code prevention.
