CP Piston & Ring Set for Subaru BRZ FA20 - Bore (86mm) - CR (9.0) - Set of 4

CP Pistons is known for making strong, well-built internal engine components, and this forged piston and ring set for the Subaru BRZ FA20 is a prime example. If you're rebuilding the heart of your BRZ or looking to handle more power, these pistons are designed to be a solid foundation. They feature an 86mm bore and a 9.0:1 compression ratio, which is a popular choice for builds that aim for a balance between street drivability and increased performance, especially when paired with forced induction.

Forged from high-strength aluminum, these pistons are significantly more durable than cast pistons, making them ideal for engines that will see higher cylinder pressures and temperatures. The set includes four pistons and their corresponding rings, ensuring you have everything needed for a complete engine build. The 9.0:1 compression ratio is a notable figure, offering a good compromise for naturally aspirated engines looking for a bit more grunt, or for turbocharged applications where it allows for more boost pressure before detonation becomes a concern. This makes them a versatile option for various performance goals.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and torque specifications to ensure proper function and longevity. Because these are performance-oriented components, they are not CARB approved and cannot be shipped to California. This set is a well-made choice for anyone serious about upgrading their Subaru BRZ's engine internals.
