About this part

Product Details

If you're rebuilding the top end of your 1991-1996 or 1999-2002 Infiniti G20, a solid head gasket is crucial for keeping everything sealed up tight. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, offering a reliable seal between your cylinder head and block without needing any extra sealants.

Cometic constructs this gasket with multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different block and head materials, like aluminum to cast iron. The center layer is uncoated stainless steel and can be varied in thickness to achieve different compressed heights; this one has a compressed operating thickness of 0.036 inches and an 87mm bore, making it a good fit for the SR20DE and SR20DET engines. The embossed layers help the gasket conform to surface irregularities, ensuring a strong seal even under high output conditions.
