Product Description
CUMMINS 3938152 OEM INTAKE MANIFOLD COVER GASKET – 5.9L (1989–2002)
Genuine Cummins 3938152 intake manifold cover gasket is the OE seal between the intake plate/manifold cover and the cylinder head on 5.9L B-series engines. Designed for 1989–2002 Dodge Ram 2500/3500 5.9L Cummins (12-valve and 24-valve), this gasket restores factory air sealing, helps maintain boost, and prevents unmetered air leaks that hurt spool-up and driveability. Built to Cummins specifications for material, thickness, and port shape, 3938152 is the correct choice when you want factory reliability instead of a generic aftermarket gasket.
Why Choose Genuine Cummins 3938152
- OE-engineered seal: Matches the original Cummins profile for proper port alignment and airflow consistency.
- Boost & drivability protection: Helps prevent boost and vacuum leaks that cause low power, lazy spool, and poor cold performance.
- Correct for 5.9L B-series: Used on many 6BT/ISB 5.9L B and QSB variants where Cummins specifies 3938152 — perfect for 1989–2002 Ram 2500/3500 and many industrial 5.9L applications (verify by ESN).
- Ideal service part: Replace any time the intake plate/manifold cover is removed for grid heater service, porting, or manifold upgrades.
- Genuine Cummins quality: Factory-approved materials and manufacturing, not a white-box or private-label gasket.

FAQ
WILL THIS FIT MY 1989–2002 5.9L CUMMINS RAM?
In most cases, yes. Cummins 3938152 is the large intake manifold cover/plate gasket used on many 1989–2002 Dodge Ram 2500/3500 trucks with the 5.9L 12V and 24V Cummins where this part number is specified. Because B-series engines have many variations, we always recommend verifying the part number by VIN or engine serial number (ESN) before ordering.
IS THIS GASKET GENUINE CUMMINS OR AFTERMARKET?
This listing is for a genuine Cummins 3938152 gasket, not an aftermarket substitute. If you are looking for a value-priced aftermarket replacement, CPP Diesel also stocks alternatives in our Interstate-McBee and other gasket lines in the Gaskets and Seals section.
DO I NEED TO USE SEALANT WITH THE 3938152 GASKET?
In most applications, Cummins specifies installing this gasket dry on clean, flat mating surfaces. Only use sealant where the Cummins service manual specifically calls for it. Excess RTV or sealant can squeeze out into the intake ports and disrupt airflow or break loose and be ingested by the engine.
HOW MANY GASKETS ARE REQUIRED PER ENGINE?
Only one Cummins 3938152 gasket is required per engine. It seals the joint between the intake manifold cover/plate and the cylinder head. If you are performing broader top-end work, also inspect the head gasket, intake horn/grid heater gasket, and other nearby seals and replace as needed.
WHAT OTHER CUMMINS PARTS SHOULD I CONSIDER WHILE I’M THERE?
When servicing the intake area on a 5.9L Cummins, many technicians also replace related gaskets and components such as the intake manifold grid heater & plenum plate (Cummins 3926381), head gasket (Cummins 3977063 on 24V applications), front gear cover gasket (Cummins 3918673), VE pump gasket on first-gen trucks (Cummins 3939355), and the oil pickup tube flange gasket (Cummins 3938157). CPP Diesel stocks these Cummins parts to help you complete the job correctly the first time.
