Cometic 06+ Mazda MZR 2.3L 89mm MLS .030in (stock thickness) Head Gasket

If you're rebuilding the top end of your 2006-2013 Mazda 3 with the MZR 2.3L engine, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of modern engines.

Cometic's MLS design uses 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 helps prevent leaks and ensures a reliable seal between the cylinder head and the engine block, whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.030 inches, matching stock specifications for an 89mm bore.

This gasket is a well-built option for your Mazda MZR engine rebuild, offering a strong seal that's ready for the job.
