Cometic C14174-024 HP Cylinder Head Gasket 78mm Bore .024" Hyundai G4FJ Gamma II

The Cometic C14174-024 is a high-performance (HP) cylinder head gasket engineered specifically for the Hyundai G4FJ Gamma II turbocharged engine. With a 78mm bore and a compressed thickness of .024 inches, this gasket is built to maintain a reliable, leak-free combustion seal under the elevated pressures and temperatures generated by forced-induction applications.

Cometic's HP gasket technology features an additional shim layer that provides increased clamping stress around the combustion seal ring, enhancing sealing performance in high-boost and high-output engine builds. The multi-layer construction uses embossed stainless steel layers coated with a proprietary high-temperature compound, allowing the gasket to conform to varying surface finishes without the need for additional sealants.
