About this part

Product Details

If you're rebuilding the top end of your VQ35DE Version 2, VQ35HR, or VQ37VHR engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid option. It's specifically designed for the left side and features a 97mm bore with a .040 inch compressed thickness, making it suitable for a wide range of Nissan and Infiniti vehicles like the 370Z, Altima, Maxima, and Infiniti G37.

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 tough sealing conditions and surface finishes up to 482°F. This construction means the gasket seals effectively without needing additional sealants, and it's built to withstand the forces created when mating aluminum heads to cast iron blocks, or aluminum to aluminum.
