Cometic Nissan VQ35DE Version 1 - VQ40DE .040in MLS Cylinder Head Gasket - 97mm Bore - RHS

If you're working on a Nissan VQ35DE or VQ40DE engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for rebuilding or performance work. It's designed to handle the demands of higher output engines, ensuring a strong seal between your cylinder head and block. This gasket is specifically sized with a 97mm bore and is .040 inches thick, intended for the right-hand side (RHS) of the engine. It fits a wide range of popular Nissan and Infiniti vehicles, including models like the Altima, Frontier, and 350Z.

Cometic builds these MLS 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 environments and varying surface finishes, meaning you don't need additional sealants. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .040 inches on this particular gasket. This construction helps manage the shearing forces that can occur between aluminum heads and cast iron blocks, making it suitable for mixed material setups.
