HKS Head Gasket

2022–Present Subaru BRZ & Toyota GR86

23002-AT005

Overview:

The HKS Grommet-Type Head Gasket is a precision-engineered component designed specifically for the Subaru BRZ and Toyota GR86 models from 2022 onward. This head gasket is crafted to meet the rigorous demands of performance tuning, particularly in turbocharged engine applications. By providing a reliable and durable seal, it ensures combustion pressures are effectively contained within the engine cylinders, which is critical for maintaining engine integrity under increased boost and tuning modifications.

Ideal for enthusiasts and professional tuners alike, this gasket supports enhanced engine performance and longevity by preventing leaks and maintaining optimal compression. Whether you are upgrading your naturally aspirated setup to a turbocharged system or seeking a robust replacement for high-boost conditions, the HKS Grommet-Type Head Gasket offers the reliability and precision required for serious performance builds.

Key Features:

Designed with advanced sealing technology, the HKS head gasket incorporates several features that make it a top choice for turbocharged Subaru BRZ and Toyota GR86 engines:

• Grommet-type design increases sealing surface pressure for superior sealing limits
• Constructed to withstand the intensified combustion pressures of turbocharged engines
• Available in a thicker 1.2 mm variant to reduce compression ratio for high-boost or rebuilt engines
• Prevents buckling between the cylinder block and cylinder head by optimizing surface pressure distribution
• Engineered to maintain durability and reliability under extreme tuning conditions
• Specifically tailored for the 2022 and newer Subaru BRZ and Toyota GR86 platforms
• Supports engine overhauls and displacement compensation without compromising seal integrity

Construction & Design:

The HKS Grommet-Type Head Gasket is manufactured using high-quality materials and advanced engineering techniques to ensure maximum durability and performance. The grommet structure enhances the gasket’s ability to maintain consistent surface pressure across the sealing area, which is essential for preventing leaks under high boost pressures. This design also helps to minimize the risk of gasket failure caused by thermal expansion and mechanical stress during aggressive driving or tuning.

Attention to detail in the gasket’s thickness options allows tuners to fine-tune compression ratios, providing flexibility for various build goals. The robust construction ensures that the gasket can handle the demanding environment of turbocharged engines while maintaining a reliable seal over extended periods.

Installation & Fitment:

The HKS Head Gasket is a direct fit replacement for the Subaru BRZ and Toyota GR86 models from 2022 onward. Installation should be performed by a qualified technician or experienced enthusiast familiar with engine disassembly and reassembly. Proper torque specifications and surface preparation are critical to ensure optimal sealing performance. This gasket is especially recommended for builds involving turbocharging or other performance modifications that increase cylinder pressures.

What's Included:
