HKS Metal Head Gasket SC 1.0mm Thick | 2013-2021 Subaru BRZ / Scion FR-S (23001-AT004)

HKS Metal Head Gasket SC 1.0mm Thick

Opposed Bead Stopper Type Metal Gasket for the FA20 engine of 86/BRZ provides higher bore sealing durability than a stock gasket. Stopper structure of the bore seal is separated type so it prevents leakage even under high gas-pressure at high engine output.

A high pressure seal is formed around the combustion chamber through the use of stoppers which create a step within the gasket for optimum sealing. By making the stopper part of the plate also allows the fold to be smaller while maintaining structural integrity. One side of the plate is completely flat meaning that it can be layered with the stopper to allow stoppers to be used in even the tightest of locations around the combustion chamber forming a high quality seal. Compared with other gaskets of the same thickness, there are more layers in these gaskets giving flexibility which allows the gasket to maintain a good seal even when the engine tries to vibrate and move.per type provide more balance in surface pressure.
