Product Details
If you're rebuilding the top end of your 1990-1998 Mazda Protege, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of a well-tuned BP motor.
Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F and works well with different block and head materials, including aluminum to cast iron. The compressed thickness is .036 inches, and this specific gasket has an 85mm bore and a .045 inch thickness, making it a good choice for engines with those specifications.
This gasket is designed to provide a reliable seal without needing additional sealants, which simplifies the installation process.
