Part Number: 23002-AT005

Description: FA24 1.2mm Thickness 11.3 CR Grommet Type Head Gasket

Fitment: 22+ Subaru BRZ / 22+ Toyota GR86

Details:

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.
