CP Piston & Ring Set for Honda H22 - Bore (87.5mm) - Size (+0.5mm) - Compression Ratio (11.5)

If you're rebuilding the engine in your Honda H22 and looking for a solid upgrade, this forged piston and ring set from CP Pistons is a great option. These pistons are designed to handle more stress than stock, making them a popular choice for performance builds or when you need to replace worn-out factory components. The 87.5mm bore with a +0.5mm oversize means they're intended for engines that have been bored out to match this size, often during a rebuild to clean up cylinder walls or increase displacement slightly.

CP Pistons are well-known for their robust construction. This set features a forged aluminum construction, which is much stronger and more durable than cast aluminum pistons. This strength is crucial for handling the increased cylinder pressures that come with a higher compression ratio, like the 11.5:1 ratio these pistons offer. This compression level is designed to increase power output when paired with appropriate tuning and fuel. The set includes the necessary rings to complete the piston assembly.

Keep in mind that this piston set is not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and torque specifications.
