HKS GR86 / BRZ Grommet Type Metal Head Gasket (1.2mm)

Overview

The HKS Grommet Type Metal Head Gasket is engineered for the Subaru FA24 engine found in the 2022+ Toyota GR86 (ZN8) and Subaru BRZ (ZD8). Designed for high-performance and forced induction applications, this multi-layer steel (MLS) gasket features HKS's reinforced grommet sealing technology to provide exceptional combustion sealing under increased cylinder pressures.

With a 1.2mm thickness and 95mm bore, this gasket lowers the engine's compression ratio compared to the factory gasket, making it an ideal choice for turbocharged builds where improved detonation resistance and reliable sealing are critical. The reinforced grommet design concentrates clamping force around each cylinder to help minimize combustion gas leakage during high-boost operation.
