Detailed Description

Mahle MS15085W is an exhaust manifold gasket set engineered for vehicles that need a dependable seal at the exhaust manifold or EGR valve interface. The steel gasket material supports consistent sealing under exhaust heat and vibration, while the OEM-standard grade makes it a practical replacement for service work on classic Pontiac models and select Buick and Oldsmobile applications. This part number, MS15085W, is commonly searched for Pontiac GTO exhaust manifold gasket set and Pontiac Firebird exhaust manifold gasket replacement needs.

This part cross-references FEL-PRO MS 9499 SH for the same application.

What It Helps Fix

• Exhaust leaks at the manifold-to-cylinder-head sealing surface
• Noise caused by a leaking exhaust manifold gasket
• Soot marks or odor from a compromised exhaust seal
• Loss of sealing integrity after manifold service or removal
• EGR valve gasket sealing concerns on listed Pontiac applications

Installation Notes and Tips

Verify engine and application details against the fitment notes before installation. For several Pontiac listings, this gasket set is specified for vehicles without Ram Air, and some applications note EGR valve gasket use or a beaded steel gasket set with adapter to block. Clean the mating surfaces thoroughly, inspect the manifold for warpage or cracks, and follow the vehicle service procedure for torque sequence and heat-cycle recheck. Confirm the correct MS15085W application before assembly.

Quality Assurance

Mahle gaskets are used as sealing components in OEM and professional repair environments, with a focus on consistent fit and material quality. MS15085W is built to OEM-standard expectations for exhaust sealing service.
