HKS Head Gasket - Grommet Type - 0.8mm - FA24 (2022+ BRZ)

The Performance requirement from Head Gasket.

As the cylinder block and head are not rigid body, when the Head Bolts are tightened, the gap between the surfaces and the surface pressure applied is not even across the whole surface. Moreover, due to combustion pressure and vibration while driving, the conditions are continually changing and the contact surface is being continually beaten. As a result, a good gasket must ensure that contact surface pressure is spread as evenly as possible and also adapt quickly to the ever changing gaps that can appear in the contact surface to maintain a good seal with good pressure.

FEATURES

• A grommet-type head gasket that supports the tuning of a vehicle with a turbocharger.

• It improves the sealing limit by securing the surface pressure of the gasket sealing surface by employing the grommet structure.

• We also have the gasket with a thickness of t = 1.2 mm, which can lower the compression ratio for dimensional correction during overhaul and for those who use it at high boost pressure.

• Buckling may cause between the cylinder head and the sealing surface of the cylinder block due to applying increased surface pressure.
