About this part

Product Details

Cometic Gasket is known for making well-built gaskets that seal reliably, and this Multi-Layer Steel (MLS) head gasket is no exception. It's built specifically for the 1991-1994 Infiniti G20, as well as compatible Nissan NX and Sentra models with the SR20DE or SR20DET engine. This gasket is designed to handle the demands of performance engines, ensuring a solid seal between your cylinder head and engine block.

This gasket uses 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 temperatures up to 482°F (250°C). This coating helps create a reliable seal, even with different block and head materials like aluminum and cast iron, and it means you don't need to add extra sealants during installation. The center layer is stainless steel, and its thickness is varied to meet specific requirements; in this case, it's set to a compressed operating thickness of 0.036 inches, and it's 0.030 inches undersize from the standard bore size, with a bore diameter of 87.5mm.
