Cometic Ford Duratech 2.3L 89.5mm Bore .034 inch MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford Duratec 2.0L and 2.3L engines, as well as Mazda L3 MZR engines. It features an 89.5mm bore and a compressed thickness of .034 inches, making it suitable for a range of vehicles like the Ford Ranger, Ford Focus, and Mazda 3.

MLS gaskets are built with 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 tough sealing environments and various surface finishes without needing additional sealants. This construction is ideal for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.

The center layer is stainless steel and can be varied to achieve different thicknesses, like the .034 inches on this particular gasket. This design helps ensure a reliable seal, even in high-output engine applications.
