About this part

Product Details

If you're rebuilding the top end of your 1997-2001 Honda Prelude, 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 the H22A4 engine.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals effectively against aluminum heads and blocks, even with different materials like cast iron. This particular gasket has a compressed thickness of 0.040 inches and an 87mm bore, making it a direct fit for the specified Prelude models. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.
