Product Details

The Cometic C4574-056 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Subaru EJ255 Version 2 and 2007-2018 EJ257 engines. This precision-engineered gasket features a .056" (1.42mm) compressed thickness and a 101mm bore diameter, making it ideal for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • 101mm bore diameter optimized for EJ255/EJ257 engine specifications
  • .056" compressed thickness for precise compression ratio tuning
  • Compatible with EJ255 Version 2 and 2007-2018 EJ257 engines
  • Engineered to withstand high boost and extreme cylinder pressures
  • Eliminates gasket failure common with stock head gaskets in performance applications

Cometic's MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to adapt to sealing surface imperfections while maintaining excellent recovery properties. This design makes them the preferred choice for turbocharged applications, engine builds with increased boost pressure, and any situation where reliability under extreme conditions is critical.
