Description

The Cometic C5512-086 is a Multi-Layer Steel (MLS) engine gasket designed for Ford Windsor V8 engines. It features a 4.060-inch bore size and a 0.086-inch thickness, constructed from 5 layers of stainless steel.

This gasket is ideal for high-output applications and provides maximum sealing without the need for additional sealants. The outer layers are coated with Viton for heat resistance, and the embossed design helps reduce bore distortion by creating an even clamp load. It is suitable for aluminum-to-aluminum and aluminum-to-cast iron applications.
