What is included in this HKS piston kit?

This kit includes all the necessary pistons, rings, wrist pins, and clips required for installation. It is designed to be a comprehensive solution for your engine build.

Why are forged pistons better for performance engines?

Forged pistons are made from a stronger aluminum alloy and undergo a forging process that creates a denser grain structure. This makes them significantly more resistant to deformation and failure under the high pressures and temperatures of a performance-tuned engine compared to cast pistons.

Can this piston kit be shipped to California?

No, this piston kit is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This is the HKS forged piston kit specifically for the FA20 engine found in vehicles like the Subaru BRZ and Scion FR-S. If you're building a performance engine or rebuilding your top end with upgraded components, a strong set of pistons is fundamental. These pistons are designed to handle increased cylinder pressures and temperatures that come with performance tuning, helping to ensure the longevity and reliability of your modified engine.

HKS has a long history in performance tuning, and this piston kit reflects that experience. They are forged from high-strength aluminum alloy, which offers a good balance of being lightweight while also being incredibly durable under stress. This forging process creates a denser, stronger grain structure compared to cast pistons, making them much more resistant to deformation and failure when you're pushing your engine hard. The kit includes all the necessary pistons, rings, wrist pins, and clips needed for installation, making it a comprehensive solution for your engine build. It's important to note that these pistons are not CARB approved and cannot be shipped to California.

When installing these pistons, proper machine work on the cylinder block and connecting rods is crucial. Ensure your machine shop is aware you are using forged pistons so they can set clearances appropriately. This kit is a solid choice for anyone looking to build a reliable, high-output FA20 engine.
