About this part

Product Details

If you're rebuilding the top end of your 1997-2001 Honda CR-V with a B20B4 or B20Z2 engine, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice. It's designed to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and engine block.

This gasket is 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. The compressed thickness is 0.070 inches, and it's made for an 85mm bore, fitting your B20 motor precisely. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.

MLS gaskets are well-suited for applications where you have aluminum heads mating to either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals.
