About this part

Product Details

If you're rebuilding the top end of your 1988-1991 Honda Prelude SI, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of your engine, ensuring a strong seal between the cylinder head and the engine block. It's designed specifically for the B20A3 and B20A5 engines found in those Prelude models.

What makes this gasket stand out is its construction. It 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 temperatures up to 482°F (250°C). This combination means it can effectively seal even with aluminum heads and cast iron blocks, and it doesn't require any additional sealants during installation, making the job a bit simpler.

With a compressed thickness of 0.045 inches and an 81.5mm bore, this gasket is ready to go on your Prelude. It's a well-built component designed for reliable performance in your engine rebuild.
