Product Details

The Cometic C4614-040 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for 2007-2012 Nissan QR25DE engines. This precision-manufactured gasket features a 90mm bore diameter and .040" (1.02mm) compressed thickness, providing exceptional sealing performance for stock and modified applications.

Key Features:

  • Multi-Layer Steel construction for superior strength and durability
  • 90mm bore diameter designed for QR25DE engine specifications
  • .040" compressed thickness for optimal compression ratio
  • Advanced coating technology ensures consistent clamp load and prevents corrosion
  • Eliminates leak paths between combustion chamber, coolant passages, and oil galleries
  • Manufactured to OEM specifications with improved material technology

Application Notes:

  • Fits 2007-2012 Nissan models with QR25DE engine
  • NOT compatible with Nissan Frontier applications
  • Designed for both stock rebuilds and performance builds

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, with an embossed viton rubber coating that provides micro-sealing at the head-to-block surface. This design allows the gasket to recover and maintain seal integrity even under extreme cylinder pressures and thermal cycling conditions.
