About Cometic Gasket

Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.

High-Performance MLS Head Gasket for Mazda B6D

Achieve the ultimate seal for your 1.6L Mazda Miata B6D engine with the Cometic Multi-Layer Steel (MLS) Head Gasket. Engineered for high-output applications, this .030-inch compressed thickness gasket is the gold standard for enthusiasts demanding reliability under boost or high-compression conditions. Cometic's advanced design utilizes multiple embossed layers of stainless steel to provide superior strength and sealing capabilities.

Key Features & Advantages

  • Material: Multi-Layer Stainless Steel with Viton rubber coating
  • Thickness: .030 inch compressed for optimal compression ratio
  • Bore Size: 80mm
  • Compatibility: Designed for Mazda 1.6L B6D engines (Miata, 323, Capri)
  • Performance: Requires no additional sealants; resists corrosion and shearing

The outer layers of the gasket are coated with Viton, a high-temperature fluoroelastomer rubber that remains stable up to 250°C (482°F). This coating ensures a superior seal even on surfaces that may have minor imperfections. Because the gasket is constructed from multiple layers of stainless steel, it has the ability to rebound during engine thermal cycling, maintaining a consistent seal between the cylinder head and engine block. Whether you are building a naturally aspirated track car or a turbocharged street machine, this gasket provides the durability to prevent leaks and protect your engine's integrity. Trust your engine build to the precision engineering of Cometic, available at GGCRACING.
