Cometic C4306-089 MLS Cylinder Head Gasket for Jaguar Engine - 3.8L XK6

The Cometic C4306-089 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for the classic Jaguar 3.8L XK6 inline-six engine. This performance gasket features an 89mm bore diameter and a compressed thickness of .089 inches, providing superior sealing and durability for both stock and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior strength and heat resistance
• 89mm bore diameter designed for Jaguar 3.8L XK6 engines
• .089" (2.26mm) compressed thickness for precise deck height control
• Embossed stainless steel layers with Viton rubber coating for optimal sealing
• Resists blowout and combustion pressure better than traditional composite gaskets
• Ideal for both restoration and performance applications

Cometic MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to recover and maintain seal integrity under extreme temperature cycling and combustion pressures. This design is particularly beneficial for classic engines like the Jaguar XK6, where maintaining proper compression and preventing coolant leaks is critical for reliable performance.
