Cometic Mazda BP-4W/BP-ZE .075in MLS Cylinder Head Gasket - 85mm Bore

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Mazda BP-4W and BP-ZE engines, featuring an 85mm bore and a compressed thickness of 0.075 inches. It's built to handle the demands of high-output engines, providing a reliable seal without needing additional sealants. This type of gasket is well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as the multi-layer steel construction can manage the stresses between different metals.

The gasket is constructed from multiple layers of stainless steel, which gives it strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482°F (250°C). This coating is designed to perform in tough sealing environments and works well on various surface finishes. The center layer is stainless steel and can be varied in thickness to meet different requirements, allowing for precise compression.

This gasket fits a range of vehicles, including popular models like the Mazda Miata, Mazda Protege, and Toyota Tacoma. It's a solid option for rebuilding or upgrading your engine's top end.
