Product Description

The Cometic C4122-051 is a high-performance MLS head gasket engineered for Mazda's 1.6 L B6 series engines (B6D, B6T, B6ZE). Its three-layer stainless steel construction, combined with a compressed thickness of 0.051 inches, provides excellent sealing strength while accommodating common deck variations. The outer layers are embossed and coated with Viton to withstand high temperatures and deliver reliable sealing under stress.

With its resilient multi-layer design, this gasket offers strong rebound characteristics that resist corrosion and maintain integrity over repeated heat cycles. It's designed for dry installation - no sealant or re-torquing is required - and works well in both standard rebuilds and high-output or race builds involving the Mazda 323, Miata, MX-3, or Mercury Capri with the B6 engine.
