• HKS Grommet Type Head Gasket (1.2mm Thickness 11.3 CR), 2022-2024 WRX

Features:
• 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.
