About this part

Product Details

When you're rebuilding the top end of your 1988-1991 Honda Prelude SI, the head gasket is a critical component. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of modern engines. It features multiple layers of stainless steel, which gives it rebound ability and corrosion resistance, making it a strong choice for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal in harsh conditions.

The center layer is uncoated stainless steel, and the overall compressed operating thickness of this gasket is 0.045 inches. This design means you don't need additional sealants, and the gasket is well-suited to withstand the shearing forces that can occur between different metal types. Cometic's MLS construction offers improved strength and sealing performance compared to traditional composite gaskets.
