About this part

Product Details

Starting with a compressed operating thickness of 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of modern engines. It's specifically designed for Nissan QR25DE 2.5L engines, featuring a 90mm bore and a 0.040 inch thickness, making it a direct fit for your 2007-2012 Altima, 2008-2013 Rogue, or 2007-2012 Sentra.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in harsh sealing environments. This construction means the gasket requires no additional sealants, simplifying installation and ensuring a reliable seal between aluminum heads and blocks, or aluminum heads and cast iron blocks, even with the shearing forces that can occur between dissimilar metals.
