HKS Stopper Type Head Gasket
2022+ Subaru BRZ & Toyota GR86 FA24 Engine
23001-AT005
Overview:
The HKS Stopper Type Head Gasket is a precision-engineered component designed specifically for naturally aspirated FA24 engines found in the 2022 and newer Subaru BRZ and Toyota GR86 models. This gasket is ideal for enthusiasts and tuners seeking to increase the engine’s compression ratio while maintaining reliable sealing performance. Its thin 0.7mm thickness is optimized to enhance combustion efficiency without compromising durability, making it a perfect upgrade for NA setups aiming for improved power delivery and throttle response.
Developed with meticulous attention to detail, the stopper type gasket addresses common challenges in high-performance applications, such as maintaining a secure seal under increased cylinder pressures and accommodating engine rebuilds involving surface grinding. This product offers a refined solution for those looking to maximize the potential of their FA24 engine while ensuring long-term reliability.
Key Features:
The HKS Stopper Type Head Gasket incorporates advanced design elements to deliver superior performance and durability. Key features include:
- Thin 0.7mm thickness to increase compression ratio, thinner than conventional grommet type gaskets (0.8mm or 1.2mm)
- Stopper structure specifically engineered for the bore seal section to ensure high sealing performance
- Thickness calibrated to compensate for surface grinding during engine overhaul
- Optimized for large-diameter bore pistons, maintaining proper pivot clearance
- Special coating applied to both head and cylinder surfaces to enhance sealing and reduce leakage
- Designed exclusively for naturally aspirated FA24 engines in Subaru BRZ and Toyota GR86 (2022 and later)
- Improves combustion efficiency by raising compression ratio without requiring extensive engine modifications
Construction & Design:
The HKS Stopper Type Head Gasket is crafted using high-quality materials and advanced manufacturing techniques to meet the rigorous demands of performance engines. The gasket’s stopper design features a reinforced sealing area around the cylinder bore, which prevents blow-by and maintains consistent compression under high load conditions. The precise 0.7mm thickness is engineered to accommodate typical surface refinishing during engine rebuilds, ensuring a perfect fit and optimal sealing.
Both the head and cylinder mating surfaces receive a specialized coating that enhances adhesion and sealing capability, reducing the risk of leaks and improving overall engine reliability. This attention to detail in construction ensures that the gasket performs consistently, even in demanding naturally aspirated applications.
Installation & Fitment:
This gasket is a direct fit replacement for the FA24 engine in 2022 and newer Subaru BRZ and Toyota GR86 models. Installation requires standard head gasket replacement procedures and may involve surface grinding or machining of the cylinder head to ensure proper sealing surface flatness. The gasket’s thickness is designed to compensate for such refinishing, making it suitable for engine overhauls and rebuilds.
Professional installation is recommended to guarantee optimal performance and longevity. No additional modifications are necessary beyond typical head gasket replacement steps.
What's Included:
- One HKS Stopper Type Head Gasket (0.7mm thickness)
Ideal For:
This head gasket is ideal for Subaru BRZ and Toyota GR86 owners with naturally aspirated FA24 engines who are seeking to increase compression ratio for improved power and efficiency. It is especially suited for enthusiasts performing engine rebuilds or overhauls who want a reliable, high-quality gasket that accommodates surface refinishing and large bore pistons. The gasket is also a great choice for tuners aiming to optimize naturally aspirated setups without resorting to forced induction.

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
