Cometic Toyota 4A-GE/4A-GEZ .070in MLS Cylinder Head Gasket - 81mm Bore - 16-Valve

This Multi-Layer Steel (MLS) head gasket from Cometic is built with an 81mm bore and a .070 inch thickness, designed specifically for the 16-valve Toyota 4A-GE and 4A-GEZ engines found in models like the MR2, Celica, and Corolla. MLS gaskets are a smart choice for high-output engines because they offer maximum sealing performance without needing any extra sealants, making them ideal for combinations of aluminum heads with either aluminum or cast iron blocks. They are well-built to handle the stresses that can occur between different metals.

The strength of this gasket comes from its multiple layers of stainless steel, which also help it resist corrosion and maintain its shape. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in tough sealing situations. The center layer is uncoated stainless steel and can be varied to achieve different gasket thicknesses, like the .070 inch on this particular part. This construction means it can handle the shearing forces created when mating dissimilar block and head materials.
