Cometic Honda K20 / K24 87.5mm Bore .040in MLS Head Gasket

If you're working on the engine of your 2002-2006 Acura RSX, or a compatible Honda CR-V or Civic from the early 2000s, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice for sealing the combustion chamber. It's specifically made for the Honda K20 and K24 series engines, with an 87.5mm bore and a compressed thickness of .040 inches, which is a common size for these applications.

Cometic builds these gaskets with multiple layers of stainless steel for strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with both aluminum and cast iron engine blocks. This design means you don't need any extra sealants; the gasket itself provides a strong seal, even under the high output conditions these engines can produce. The center layer is stainless steel and can be varied to achieve different thicknesses, but this specific gasket is set at .040 inches compressed.
