About this part

Product Details

Starting with a multi-layer steel (MLS) construction, this Cometic head gasket is built for the demands of high-output engines. The outer layers are coated with Viton, a heat-resistant rubber material rated up to 482°F, ensuring a solid seal even under tough conditions. This design means you won't need additional sealants, simplifying the installation process.

The gasket features an 86mm bore and a compressed thickness of 0.036 inches, with an initial thickness of 0.040 inches. Its multi-layer stainless steel design provides increased strength and resistance to corrosion, while also allowing the gasket to rebound effectively. This construction is suitable for mating aluminum heads to either aluminum or cast iron blocks, handling the shearing forces that can occur between different metals.

This gasket is specifically designed for the 1994-1997 Mazda Miata, as well as the 1994 323 and 1994-1997 Protege. It's a well-built option for rebuilding or upgrading your engine's top end.
