HKS Grommet Type Head Gasket – 23002-AT002

If you’re tuning your Subaru BRZ with the FA20 engine, you might be aware of the common issue of head gasket failure, especially when using turbo or supercharging setups. The HKS Grommet Type Head Gasket, model 23002-AT002, is designed to tackle this challenge head-on, providing a robust solution that outperforms traditional stopper-type gaskets.

Key Features:

• Improved Gas Seal: The gasket maintains gas seal surface pressure, enhancing the sealing limits for a more reliable performance.
• Strengthened Design: When paired with reinforced head bolts, this gasket offers superior sealing strength, ideal for high-performance applications.
• Versatile Thickness Options: Compatible with existing stopper-type gaskets, it provides a variety of thicknesses, giving you flexibility in adjusting your compression ratios.

Specifications:

• Model: 23002-AT002
• Fitment: Subaru BRZ FA20 (2013-2020)
• Material: Advanced grommet type for enhanced sealing

Important Note:

While the high surface pressure of this gasket significantly improves performance, it can lead to warping of the block or heads. To counteract this, a high-thickness option is available, allowing for adjustments based on head or block machining.
