Detailed Description

Apex AMS8551 is an exhaust manifold gasket set for vehicles that require a reliable seal between the exhaust manifold and cylinder head. This part supports service work on a wide range of compact Toyota-based platforms, including the Toyota Corolla, Toyota Matrix, and Pontiac Vibe, with additional coverage for the Celica, MR2 Spyder, and Chevrolet Prizm. If you are replacing a leaking exhaust manifold gasket on a 1998-2008 Toyota Corolla or a 2003-2008 Toyota Matrix, AMS8551 provides the correct application match.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Exhaust leaks at the manifold-to-head sealing surface
• Ticking or puffing noises from a leaking manifold gasket
• Loss of exhaust sealing after manifold service
• Replacement needs during cylinder head or exhaust manifold repair
• Fitment matching for Toyota Corolla, Matrix, and Pontiac Vibe service jobs
