Product Details

The Cometic C4122-040 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Mazda B6D, B6T, and B6ZE engines. This high-performance gasket features an 80mm bore diameter and a compressed thickness of .040 inches (1.02mm), making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • 80mm bore diameter designed for Mazda B6-series engines
  • .040" compressed thickness for precise compression ratio control
  • Advanced material composition withstands extreme temperatures and pressures
  • Eliminates gasket failure and coolant leaks common with OEM gaskets
  • Suitable for turbocharged (B6T) and naturally aspirated (B6D, B6ZE) applications

Cometic's MLS gaskets utilize multiple layers of stainless steel with advanced coatings to create a superior seal that conforms to irregular sealing surfaces. This design accommodates engine movement and flexing while maintaining consistent cylinder pressure, making it the preferred choice for enthusiasts building Mazda B6-powered vehicles including the Miata, 323, Protege, and Capri.

Specifications:

  • Bore: 80mm (3.150")
  • Compressed Thickness: .040" (1.02mm)
  • Material: Multi-Layer Steel (MLS)
  • Engine Compatibility: Mazda B6D, B6T, B6ZE
