Product Details

The Cometic C4125-059 is a precision-engineered cylinder head gasket designed specifically for the classic Jaguar 3.8L XK6 engine. This high-performance gasket features Cometic's advanced CFM-20 (Compressed Fiber Material) construction with a compressed thickness of .059 inches, providing exceptional sealing capability and durability.

Key Specifications:

  • Bore size: 89mm for precise fitment to Jaguar XK6 cylinder specifications
  • Compressed thickness: .059 inches (1.5mm) for optimal sealing under compression
  • CFM-20 gasket material provides superior conformability and resistance to high temperatures
  • Engineered to withstand the thermal cycling and combustion pressures of classic Jaguar inline-six engines
  • Direct replacement for Jaguar 3.8L XK6 applications

Cometic's CFM-20 material technology combines aramid fibers with a fluoroelastomer coating, creating a gasket that excels in both street and performance applications. This design ensures reliable sealing across the entire combustion chamber while accommodating minor surface imperfections. Ideal for engine rebuilds, restorations, or performance upgrades on classic Jaguar XK-series engines.
