HKS Head Gasket

2013–2020 Subaru BRZ / 2013–2016 Scion FR-S / 2017–2020 Toyota 86 FA20 Engine

23002-AT001

Overview:

The HKS Grommet Type Head Gasket is engineered specifically for the FA20 engine found in the Subaru BRZ, Scion FR-S, and Toyota 86 models from 2013 through 2020. As turbocharging and supercharging become increasingly popular upgrades for these vehicles, the factory head gasket can often become a weak point under boosted conditions. This gasket addresses that issue by offering enhanced sealing strength and durability, making it an essential upgrade for enthusiasts pursuing forced induction or high-performance tuning.

Designed for performance enthusiasts and tuners, this gasket helps maintain engine reliability and compression integrity even under increased cylinder pressures. Whether you are upgrading your vehicle for street performance or track use, the HKS Grommet Type Head Gasket provides a robust solution to head gasket failure commonly encountered during aggressive tuning.

Key Features:

This head gasket incorporates advanced design elements to ensure superior sealing and durability under demanding conditions:

• Maintains a 10.8:1 compression ratio, optimized for performance tuning.
• Grommet-type design improves gas seal surface pressure, increasing sealing limits beyond traditional stopper-type gaskets.
• Strengthened head bolts included to deliver higher clamp load and enhanced seal strength.
• Compatible with existing stopper-type gaskets, allowing a wide range of thickness options for customized compression ratio adjustments.
• High surface pressure design accounts for potential block and head warping during high-performance use.
• Available in higher thickness options to compensate for head or block machining, ensuring proper fitment and sealing.

Construction & Design:

The HKS Grommet Type Head Gasket is crafted with precision materials and engineering to withstand the increased stresses of turbocharged and supercharged FA20 engines. The grommet design enhances the sealing surface pressure around critical combustion areas, reducing the risk of leaks and failures common in boosted applications. Combined with reinforced head bolts, this gasket maintains a reliable seal even under elevated cylinder pressures.

Additionally, the availability of multiple thicknesses allows tuners and engine builders to fine-tune compression ratios and compensate for any machining performed on the cylinder head or block. This flexibility ensures optimal engine performance and longevity.

Installation & Fitment:

This gasket is a direct replacement for the factory head gasket on the Subaru BRZ (2013–2020), Scion FR-S (2013–2016), and Toyota 86 (2017–2020) equipped with the FA20 engine. It is designed to work seamlessly with OEM components and mounting points.

Installation should be performed by a professional or experienced technician familiar with engine disassembly and reassembly. Proper torque specifications and installation procedures must be followed to achieve the best sealing results and avoid engine damage.
