23001-AT004

Overview:

The HKS Metal Head Gasket is engineered specifically for the Subaru BRZ, Scion FR-S, and Toyota 86 models spanning 2013 through 2020. Designed to support high-performance applications, this gasket is ideal for enthusiasts upgrading their engines with superchargers, turbochargers, or HKS Capacity Upgrade Kits. It allows for precise adjustment of the compression ratio, helping you maximize power output while maintaining reliable sealing under extreme conditions.

Whether you are tuning your vehicle for spirited street driving or track use, this gasket provides the durability and sealing performance needed to handle increased cylinder pressures without compromise.

Key Features:

This HKS metal head gasket incorporates advanced design and materials to ensure superior sealing and reliability for boosted and high-output engines.

• Thickness of 1.0mm tailored for use with HKS Capacity Upgrade Kits and forced induction setups.
• Opposed bead stopper type design with a separated bore seal structure to prevent leakage under high gas pressure.
• Special coating applied on both the head and cylinder sides to enhance sealing performance during bolt tightening.
• Improved contact surface pressure ensures a tight seal even at elevated engine outputs.
• Endurable construction capable of withstanding the demands of supercharged and turbocharged engines.
• Allows for a wider compression ratio adjustment range when installed with supercharger systems.

Construction & Design:

The gasket features a metal construction optimized for high-pressure environments common in upgraded Subaru BRZ, Scion FR-S, and Toyota 86 engines. The opposed bead stopper design separates the bore seal structure, effectively preventing gas leakage even under extreme combustion pressures. This design enhances durability and reliability, critical for engines running forced induction or increased displacement.

Additionally, the special coating applied to both the head and cylinder contact surfaces improves bolt torque retention and sealing integrity, reducing the risk of gasket failure during high-stress operation.

Installation & Fitment:

This gasket is a direct fit replacement for the following vehicles:

• Subaru BRZ (2013–2020)
• Scion FR-S (2013–2016)
• Toyota 86 (2017–2020)

Installation requires standard head gasket replacement procedures. It is designed to work seamlessly with HKS Capacity Upgrade Kits and forced induction setups, enabling compression ratio adjustments without compromising sealing performance. No special modifications beyond typical engine disassembly are necessary.
