Cometic Mazda BP-4W/BP-ZE .045in MLS Cylinder Head Gasket 85.5mm Bore

When you're rebuilding the top end of your 1990-1998 Mazda Protege, a solid cylinder head gasket is crucial for a good seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines. It's designed to provide maximum sealing performance without needing any extra sealants, making the installation process more straightforward.

This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. The center layer is stainless steel, and its thickness can be varied to meet different requirements; in this case, it's set to provide a compressed operating thickness of 0.036 inches with an 85.5mm bore, perfect for many BP-4W and BP-ZE engines. MLS gaskets are a good choice for sealing aluminum heads to either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals.
