CP Piston & Ring Set for Subaru BRZ FA20 - Bore (86.5mm) - CR (10.5) - Set of 4

If you're building a high-performance engine for your Subaru BRZ FA20, especially one that will see track time or forced induction, a strong set of pistons is fundamental. This CP Pistons set is designed to handle the increased stress and heat that come with a modified engine. They are forged from high-grade aluminum, which is a strong material that can withstand significant pressure and temperature changes without deforming. This means your engine can operate reliably under demanding conditions.

Each piston in this set has a bore size of 86.5mm and a compression ratio of 10.5:1. This specific compression ratio is a popular choice for many performance builds, offering a good balance between power output and the ability to run safely with boost or higher octane fuels. The pistons are paired with a set of rings, which are crucial for sealing the combustion chamber, controlling oil, and transferring heat to the cylinder walls. CP Pistons is a well-known name in the performance aftermarket, and this set reflects their focus on durability and performance for serious engine builds. You'll want to ensure you have the proper tools and knowledge for installation, as this is a critical component for engine longevity and performance.

This set includes four pistons and their corresponding rings, ready for installation into your FA20 engine. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for precise details on fitting these pistons into your engine block.
