Product Details

The Cometic C4306-140 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for the classic Jaguar 3.8L XK6 inline-six engine. This high-performance gasket features a compressed thickness of .140 inches and an 89mm bore diameter, providing superior sealing for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
  • 89mm bore diameter designed for Jaguar XK6 engine specifications
  • .140 inch (3.56mm) compressed gasket thickness
  • Superior torque retention and reusability compared to composite gaskets
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Provides excellent resistance to combustion gases and coolant

Cometic MLS gaskets are constructed from multiple layers of stainless steel with a Viton rubber coating, allowing them to recover and maintain torque loads better than traditional gaskets. This design is ideal for classic Jaguar XK engines found in E-Type, Mark 2, and other vintage Jaguar models equipped with the legendary 3.8L XK6 powerplant.
