Construction & Design

The HKS FA20 Grommet Type Head Gasket features a robust construction utilizing premium materials designed to endure the rigors of high-performance applications. Its grommet-style design provides a more reliable seal by evenly distributing surface pressure across the cylinder head and block interface. This design minimizes the risk of gasket buckling or deformation under high-boost conditions, which is a common challenge with traditional stopper-type gaskets.

The gasket's high-strength composition ensures it maintains its integrity during thermal cycling and mechanical stresses, making it suitable for supercharged setups that operate at elevated pressures. The precise engineering and manufacturing processes employed by HKS guarantee a perfect fit for the Subaru FA20 engine, facilitating straightforward installation and long-lasting performance.

Installation & Fitment

The HKS FA20 Grommet Type Head Gasket is designed as a direct replacement for the factory gasket on Subaru FA20 engines. Installation involves removing the cylinder head and replacing the existing gasket with this upgraded component. Due to its precise engineering, no additional modifications or tuning are typically required, although it is recommended to follow proper engine assembly procedures and torque specifications.

Given its high-quality construction and exact fitment, the gasket provides a straightforward installation process for experienced technicians or enthusiasts with mechanical skills. It is essential to ensure the sealing surfaces are clean and free of debris before installation to achieve optimal sealing performance. This gasket is suitable for use in supercharged applications, high-boost setups, and other high-performance modifications.
