Cometic C4338-059 Cylinder Head Gasket for Jaguar Engine - 4.2L XK6

The Cometic C4338-059 is a high-performance cylinder head gasket engineered specifically for 1964-1968 Jaguar 4.2L XK6 inline-six engines. This precision-manufactured gasket features a 93mm bore diameter and .059-inch (1.5mm) compressed thickness, providing optimal sealing and compression control for classic Jaguar powerplants.

Key Features:

• CFM-20 gasket material construction for superior heat resistance and durability
• 93mm bore diameter designed for Jaguar XK6 cylinder dimensions
• .059-inch compressed thickness for precise compression ratio management
• Multi-layer steel (MLS) design ensures consistent clamping pressure across the entire sealing surface
• Engineered to handle the thermal expansion characteristics of vintage aluminum and cast iron engine blocks
• Eliminates common leak paths found in original equipment gaskets

Cometic gaskets are manufactured using advanced materials and processes that provide excellent conformability to imperfect sealing surfaces, making them ideal for both stock restorations and performance builds. The CFM-20 material offers exceptional resistance to coolant and oil while maintaining consistent sealing under varying temperature conditions typical in classic British engines.
