Overview

GM Genuine Parts Exhaust Manifold Gaskets are designed, engineered, and tested to the high standards General Motors sets for OE parts.

These gaskets are part of the lineage of GM OE parts, reflecting the brand’s commitment to factory-level fit and durability. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

What this gasket does

• Helps prevent exhaust leaks by sealing the joint where the manifold meets the engine block
• Supports a tight, long-lasting seal at the exhaust manifold mounting surface

The gasket is built to withstand the typical conditions of an engine bay, including heat cycling and exposure to exhaust gases, contributing to predictable service intervals and peace of mind. While individual results can vary, a genuine gasket often complements a well-maintained exhaust system by preserving seal integrity and reducing the chance of future leaks.
