CP Piston & Ring Set for Acura/Honda K20A/A2/A3 - Bore (87mm) - (+1.0mm) - CR (10.9) (Single Piston)

Forged from high-strength aluminum alloy, this CP Pistons piston and ring set is built for performance applications on Acura and Honda K20A, K20A2, and K20A3 engines. This set is designed for an 87mm bore and is a +1.0mm oversize, meaning it's intended for engines that have been bored out to accommodate this larger size, often during a rebuild or performance upgrade. The compression ratio is set at 10.9:1, which is a notable increase over stock, helping to generate more power from your fuel and air mixture.

CP Pistons are well-known for their robust construction, and this set is no exception. The forged process creates a stronger, more durable piston compared to cast aluminum, making it better suited to handle the increased cylinder pressures and temperatures found in modified or high-performance engines. This particular set is for a single piston and includes the necessary rings, ready for installation in your K-series engine build. Remember, this part is not CARB approved and cannot be shipped to California.
