Product Description

The Cometic C4122-045 is a high-performance MLS head gasket designed for Mazda's 1.6 L B6 family of engines, including the Miata, 323, MX-3, and Mercury Capri. Built with three stainless-steel layers, it offers excellent strength, heat resistance, and sealing capability, even when used on demanding high-performance or rebuild applications.

With a compressed thickness of 0.045 inches and a precise 80 mm bore size, this gasket is engineered to maintain a tight seal across the combustion chamber while accommodating common deck tolerances. The outer steel layers are coated with Viton for superior sealing, and it's designed for dry installation (no sealants needed) and no re-torque, making it ideal for both daily driving or high-stress builds.
