Details:
The HKS Japan grommet-type head gasket is designed to be used for increased boost pressures and high engine combustion pressures in the G16E-GTS engine.

HKS Grommet type
- It improves the sealing limit by securing the surface pressure of the gasket sealing surface by employing the grommet structure.
- It put the shims at either end of the engine deck to apply the load evenly when tightening the head bolt to prevent the distortion of the cylinder head.
