About this part

Product Details

If you're working on the 4A-GE engine in your 1985-1989 Toyota MR2, or a 1985-1988 Corolla, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice for sealing your cylinder head. It's specifically made for an 81mm bore and has a compressed thickness of .120 inches, which is a common size for these engines.

Cometic builds these gaskets with 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 high temperatures up to 482°F (250°C) and works well with both aluminum and cast iron engine blocks. This construction means the gasket seals tightly without needing any extra sealants, making installation more straightforward and reliable, especially in high-output engine builds.
