About this part

Product Details

If you're rebuilding the top end of your 2002-2006 Acura RSX, or a compatible Honda K-series engine, a quality head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines without needing extra sealants.

Cometic's MLS design uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, making it suitable for aluminum heads on either aluminum or cast iron blocks. The center layer is stainless steel and can be varied to achieve different compressed thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches, with an initial bore size of 90mm and an undersize of .030 inches.
