Product Details

The Cometic C4623-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for the Subaru EZ30D Mark II engine. This precision-engineered gasket features a 90mm bore diameter and .030" (0.76mm) compressed thickness, making it ideal for performance builds and engine rebuilds requiring enhanced sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 90mm bore diameter designed for Subaru EZ30D Mark II engines
  • .030" compressed thickness for precise compression control
  • Left-hand side (LHS) application
  • Enhanced combustion sealing to prevent leaks and gasket failure
  • Accommodates thermal expansion and engine movement
  • Engineered for performance and OEM+ applications

Cometic's MLS gaskets feature multiple layers of stainless steel with specialized coatings that provide exceptional resistance to extreme temperatures and pressures. The embossed active sealing area ensures consistent clamping pressure distribution, while the flexible design compensates for minor surface imperfections and engine distortion. This gasket is essential for maintaining proper compression and preventing coolant or oil leaks in your Subaru EZ30D engine.
