This listing is for a single CP Pistons forged piston designed for the Acura B18C1 engine. It features a bore size of 81.5mm and is a +0.5mm oversize piston, meaning it's intended for engines that have been bored out to accommodate this larger size. The piston is designed to achieve a 9.0:1 compression ratio.

CP Pistons are known for their well-built forged construction, which offers improved strength and durability compared to cast pistons, making them a solid option for performance builds. This piston is specifically sized for a 0.5mm overbore, which is common when rebuilding an engine to restore cylinder wall integrity or to increase displacement slightly. The 9.0:1 compression ratio is a moderate figure, suitable for a wide range of applications, including those that may use forced induction or require a balance between power and pump gas compatibility.

Please note that this piston is not CARB approved and cannot be shipped to California. Always consult with your engine builder or mechanic to ensure this specific piston meets the requirements of your build.
