Description

The Cummins Intake Valve Kit 3802355 is a precision-engineered diesel engine valve kit designed to ensure proper airflow, combustion efficiency, and reliable valve train operation in Cummins diesel engines. This kit is a direct replacement for Cummins OEM part numbers 3901117 and 3906854 , making it ideal for cylinder head service, valve train repairs, and complete engine rebuilds. Manufactured from high-strength, heat-resistant alloy steel , the intake valves in this kit are built to withstand high combustion temperatures, continuous valve cycling, and heavy-duty operating conditions . The precision-machined valve faces and stems ensure accurate seating, reduced wear, and long service life under demanding diesel engine loads. Designed for accurate fitment and consistent performance , the Cummins 3802355 intake valve kit helps restore proper air intake flow, supports efficient combustion, and maintains correct valve timing. Replacing intake valves during a cylinder head overhaul is critical to preventing power loss, poor fuel efficiency, and premature valve train wear. This intake valve kit is commonly used as part of an upper gasket set or valve train service in Cummins diesel engine rebuild and cylinder head repair applications , including on-highway trucks, industrial engines, and heavy-duty equipment.
