Cometic BMW 318/Z3 89-98 86mm Bore .140 inch MLS Head Gasket M42/M44 Engine

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your BMW M42 or M44 engine. If you're rebuilding the top end of your 1991-1998 BMW 318i, 318is, 318ti, or 1996-1998 Z3, a quality head gasket is crucial for proper engine function, keeping combustion pressures contained and coolant and oil separated. This gasket is built to handle the demands of these engines.

This MLS gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes, meaning you don't need additional sealants. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.140 inches and an 86mm bore, designed to match your engine's specifications. It's suitable for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between different metals.
