About this part

Product Details

When you're rebuilding the top end of your engine, a solid head gasket is crucial for sealing the combustion chambers and coolant passages. This Multi-Layer Steel (MLS) head gasket from Cometic is built for engines that need dependable sealing, especially those with higher performance expectations. It's designed to handle the pressures and temperatures found in engines like the Nissan L28E/S/ES non-turbo, and also fits a range of Mazda models including the 1994-1997 Miata.

What you get here is a well-built gasket made from multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps create a strong seal against the cylinder head and block, even with different materials like aluminum heads on cast iron blocks. The center layer is stainless steel and can be varied in thickness to achieve the precise compressed operating thickness of 0.036 inches, ensuring a good seal without needing extra sealants.

This gasket is a popular choice for engine builds where reliability is key. Its multi-layer construction offers increased strength and resistance to corrosion, making it a solid option for keeping your engine running smoothly.
