Engine Sealing Performance for Mazda BP Engines

Engineered for high-performance applications, this 84mm bore gasket features a .040-inch compressed thickness, ideal for maintaining optimal compression ratios in both naturally aspirated and forced induction setups.

Advanced Multi-Layer Steel Construction

Cometic utilizes a high-grade stainless steel multi-layer design that provides superior rebound and torque retention compared to factory gaskets. The outer layers are embossed and coated with a heat-resistant Viton rubber, capable of withstanding temperatures up to 482°F (250°C). This construction ensures excellent performance even under the harsh sealing environments of high-boost or high-RPM driving.
