Product Details
When you're rebuilding the top end of your 1991-1994 Infiniti G20, or any Nissan SR20DE/DET engine from those years, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines. It's designed to provide a strong seal between your cylinder head and engine block, helping to keep combustion pressures contained and coolant and oil where they belong.
What you get here is a well-built MLS gasket. It's made with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C), making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron engine configurations. This gasket has a compressed operating thickness of 0.040 inches and is designed for an 87.5mm bore, fitting the SR20DE and SR20DET engines, including AWD applications.
Because it's an MLS gasket, it doesn't require any additional sealants, which simplifies the installation process. Just make sure your mating surfaces are clean and flat, and this gasket will do the rest.
