Cometic Nissan 2007-2012 QR25DE .051in MLS Cylinder Head Gasket - 90mm Bore - EXCEPT Nissan Frontier

If you're working on the QR25DE engine in your 2007-2012 Nissan Altima, Rogue, or Sentra, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing the cylinder head to the block. It's designed to handle the demands of modern engines, ensuring a strong seal without needing extra sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C). This combination of materials is ideal for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the different expansion rates and shearing forces between these metals. The center layer is stainless steel and can be varied in thickness, with this particular gasket having a compressed operating thickness of 0.036 inches and a bore size of 90mm, specified at 0.051 inches thick before compression.
