HKS FA20 89.5mm Bore 1.2mm Thick Grommet Type Head Gasket is a premium 1.2mm thick, 89.5mm bore grommet-type metal head gasket for the Subaru/Toyota FA20 engine, designed for high-boost turbo/supercharger setups. It increases sealing pressure to prevent gasket failure and is ideal for 2013–2021 BRZ/FRS/86 engines, often used with reinforced head studs for maximum durability.

  • Grommet Technology: Provides higher gas seal surface pressure than traditional stopper-type gaskets, improving sealing limits.
  • Engine Suitability: Specifically designed for the FA20 engine found in the Subaru BRZ, Toyota 86, and Scion FRS (2013-2021).
  • Durability: Ideal for high-horsepower or forced induction builds to prevent gasket failure.
  • Independent Bead: Features independent beads for water and head bolt holes to improve sealing and prevent cracking around head bolts.
  • High Compression Setup: Provides a 10.4 compression ratio when used with HKS low-comp pistons.
    • Subaru BRZ (2013–2021)
    • Toyota 86 (2017–2021)
    • Scion FR-S (2013–2016)
