Detailed Description

Mahle MS20146 is a fuel injection plenum gasket used to seal the intake plenum assembly on specific Buick, Chevrolet, Pontiac, and Saturn models. This gasket is listed for 2004-2007 applications and is specified with throttle body and EGR gasket coverage, making it a practical replacement when servicing the upper intake sealing surfaces. Mahle gaskets are known for consistent sealing quality in OEM-style repair work, and this part number is a direct match for the listed vehicles.

For buyers searching for a 2006 Buick Rendezvous plenum gasket, a 2005 Chevrolet Uplander throttle body gasket, or a 2005 Pontiac G6 EGR gasket, MS20146 is the relevant part number to verify against the application.

What This Part Helps Address

• Intake plenum vacuum leaks
• Air leakage at the throttle body sealing surface
• EGR sealing issues during intake service
• Rough idle caused by deteriorated upper intake gaskets
• Loss of sealing integrity after manifold or plenum removal

Installation Notes and Tips

Clean the mating surfaces thoroughly before installation and inspect the intake components for warpage, carbon buildup, or damage. Confirm vehicle year, make, and model against the listed fitment before ordering MS20146. This gasket is used on the specified Buick Rendezvous, Chevrolet Malibu, and Pontiac G6 applications, so matching the exact engine-side sealing layout is important during service.

Quality Assurance

Mahle supplies sealing products used by OEMs and professional technicians worldwide. MS20146 is produced as an OE-style sealing component for the listed GM applications, with fitment and sealing performance aligned to the original service requirements.
