Cometic Mazda FS-DE/FS-DET .045in MLS Cylinder Head Gasket - 84mm Bore

If you're rebuilding the top end of your 1993-2002 Mazda 626, especially if it's a performance build with the FS-DE or FS-DET engine, a reliable head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of higher output engines, ensuring a solid seal between your cylinder head and engine block.

This gasket is constructed from 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 (250°C). This combination makes it suitable for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the different expansion rates between these materials. The compressed operating thickness is 0.045 inches, and the bore is 84mm, designed to match your engine's specifications without needing additional sealants.

Cometic's MLS design is a popular choice for engines that see increased stress. It offers a robust sealing solution that holds up well in demanding conditions.
