Cometic Mazda Miata 1.6L 80mm .070 inch MLS Head Gasket B6D Motor

If you're rebuilding the top end of your 1988-1993 Mazda 323, a quality head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the pressures of a well-running engine.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F. This coating ensures a reliable seal against the engine block and cylinder head, even with different materials like aluminum heads and cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches and is 0.070 inches thick before compression, with an 80mm bore diameter, making it suitable for the B6D motor.

This gasket is designed to provide maximum sealing performance without needing additional sealants, making installation more straightforward. It's a solid option for ensuring a good seal in your Mazda's engine.
