Cometic BMW 04-UP 4.4L V8 94mm .051 inch MLS Head Gasket 545/645/745/ X5 4.4i

Built with multiple layers of stainless steel, this Cometic Multi-Layer Steel (MLS) head gasket features an outer layer coated with Viton, a heat-resistant rubber material rated up to 482°F. This construction is designed to handle the high output of modern engines and provides maximum sealing performance without needing additional sealants. It's suitable for sealing aluminum heads to aluminum blocks, or aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals.

The center layer of stainless steel can be varied to achieve different thicknesses, and in this case, the compressed operating thickness is .051 inches with a 94mm bore. The multiple stainless steel layers give the gasket increased strength and the ability to rebound, while also resisting corrosion. This gasket is a solid option for your BMW 4.4L V8, fitting models like the 545i, 645Ci, 745i, and X5 from the mid-2000s.
