About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) cylinder head gasket is a prime example. It's specifically made for the 1988 through 1991 Honda Prelude models equipped with the B20A3 or B20A5 engine. This gasket is crucial for keeping your engine's combustion chambers sealed from the oil and coolant passages, preventing leaks and ensuring proper engine operation.

This gasket is constructed from three to five layers of stainless steel. Using stainless steel gives it increased strength and helps it resist corrosion and maintain its shape under pressure. The outer layers are embossed and then coated on both sides with a Viton rubber material. This coating is designed to handle tough sealing jobs, various load conditions, and different surface finishes on your engine block and cylinder head. The Viton coating itself can handle temperatures up to 482°F (250°C), which is important for keeping a seal in the hot environment of an engine's cylinder head.
