Cometic Jaguar 3.8L XK6 .018in MLS Cylinder Head Gasket - 89mm Bore

When you're rebuilding the top end of your Jaguar 3.8L XK6 engine, or perhaps a Mazda Miata or Protege from the mid-90s, a reliable head gasket is crucial. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of performance engines, ensuring a strong seal between your cylinder head and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel and can be varied in thickness to meet different requirements; this particular gasket has an operating thickness of 0.036 inches when compressed, and it's designed for an 89mm bore. MLS gaskets are ideal for joining aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can manage the shearing forces that can occur between dissimilar metals.

Because these gaskets are well-built with advanced materials, they don't require any additional sealants, making installation more straightforward. This gasket fits a range of vehicles, including Jaguar models like the Mark IX, Mark X, and XK150, as well as Mazda 323, Miata, and Protege models from the mid-90s.
