The HKS 1.0mm Thick Metal Head Gasket for Subaru BRZ and Scion FR-S is a high-performance replacement gasket designed for the FA20 engine. Constructed from durable metal, this opposed bead stopper type gasket enhances bore sealing durability compared to the stock component. Its stopper structure prevents leakage under high gas-pressure conditions, making it suitable for high-output applications. The gasket features a stepped stopper design that creates a high-pressure seal around the combustion chamber, ensuring reliable sealing during aggressive driving or tuning. Its robust construction and precise engineering deliver improved sealing performance, contributing to increased engine reliability and potential power gains.

This gasket is compatible with Subaru BRZ and Scion FR-S models from 2013 to 2021. It is intended for use in high-performance or modified engines where enhanced sealing is required to handle increased boost or compression. The installation involves replacing the stock head gasket with this metal variant, providing a direct fit for FA20 engines. Ideal for street, track, or tuning enthusiasts, this gasket supports high-pressure environments and helps maintain optimal engine performance under demanding conditions. The kit includes the metal head gasket designed specifically for the FA20 engine, ensuring a secure and reliable seal.

Overview

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.
