Product Details

The Cometic C4278-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Toyota 7M-GE and 7M-GTE engines. This gasket features a .030" (0.76mm) compressed thickness and is designed for an 84mm bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high temperatures and pressures
  • 0.030" compressed thickness allows for precise compression ratio tuning
  • 84mm bore diameter designed for Toyota 7M-GE naturally aspirated and 7M-GTE turbocharged inline-six engines
  • Advanced coating technology ensures optimal clamp load retention and resistance to corrosion
  • Designed to withstand extreme cylinder pressures in boosted and high-performance applications
  • Eliminates the need for additional sealants when installed properly with correct torque specifications

Cometic MLS gaskets are the choice of professional engine builders and performance enthusiasts worldwide. The multiple layers of stainless steel with active sealing beads conform to imperfections in the block and head surfaces, providing exceptional combustion sealing even in demanding racing and street performance applications. This gasket is compatible with Toyota Supra and Cressida models equipped with 7M-series engines.
