About this part

Product Details

CP Pistons is known for making strong internal engine components, and this forged piston for Honda K20A and K20A2 engines is a great example of their work. If you're rebuilding the top end of your K-series engine and need a reliable piston, this is a solid option. It's designed to fit K20A and K20A2 engines and comes in a +3.0mm oversize, meaning it's meant for engines that have been bored out to 89.0mm.

This piston features an 11.5:1 compression ratio, which is a notable bump over stock, giving you improved performance potential. Forged pistons like this one are built to handle higher cylinder pressures and temperatures compared to cast pistons, making them a popular choice for builds that see more demanding use. The included ring set is designed to work with this specific piston, ensuring a good seal in the cylinder bore.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
