Reliable Sealing for High-Horsepower Subaru Builds

The Cometic 101mm .051" MLS Head Gasket is engineered to meet the demands of high-performance Subaru EJ255 and EJ257 engines. When you are building a motor for increased boost and power, the head gasket is the most critical component for maintaining cylinder pressure. Cometic’s multi-layer steel technology provides an unparalleled seal that stands up to the extreme thermal and mechanical stresses of a turbocharged engine.

Engineered for Performance

• High-Strength Steel: Multi-layer construction ensures the gasket resists blowout under high boost.
• Viton Coating: Advanced rubber coating provides a superior seal, even on surfaces that are not perfectly smooth.
• Thermal Resilience: Withstands temperatures up to 250°C, ensuring long-term reliability.
• Precision Sizing: The 101mm bore size is ideal for engines that have been bored out for increased displacement.

The .051" thickness is a popular choice for builders looking to adjust their compression ratio or accommodate specific piston-to-head clearances. By choosing Cometic, you are investing in a product that has been proven on tracks worldwide. Its ability to rebound and maintain its seal through multiple heat cycles makes it the preferred choice for tuners and engine builders.
