HKS SMG/K FA20 t=1.0

The HKS 1mm Thick Opposed Bead Stopper Type Metal Head Gasket is designed to enhance engine performance and reliability for high-output engines, especially with forced induction setups like superchargers and turbochargers. Its unique stopper structure prevents leakage under extreme gas pressures, ensuring a secure seal. Both the cylinder and head sides are coated with a special sealing layer that increases contact surface pressure, maintaining tightness when bolts are torqued. The 1mm thickness allows for precise compression ratio adjustments, making it ideal for Capacity Upgrade Kits and fine-tuning engine performance.
