Product Details

The Cometic C4122-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Mazda B6D, B6T, and B6ZE engines. This precision-crafted gasket features an 80mm bore diameter and .030" compressed thickness, making it ideal for modified engines running higher compression ratios or boost levels.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 80mm bore diameter designed for Mazda B6-series engines
  • .030" (0.76mm) compressed gasket thickness
  • Compatible with B6D, B6T (turbocharged), and B6ZE engine variants
  • Excellent for turbocharged and high-performance applications
  • Provides improved combustion sealing over stock gaskets
  • Resists blow-out under extreme cylinder pressures

Cometic's MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to create a superior seal between the cylinder head and engine block. The .030" thickness makes this gasket thicker than stock, effectively lowering compression ratio slightly—beneficial for forced induction applications or when using aftermarket pistons. This gasket is a popular choice among Mazda enthusiasts building B6-powered vehicles like the Miata, 323, and Protege for racing or street performance.
