CP Piston & Ring for Acura/Honda K20A/A2/A3 89mm Bore - Size +2.0mm - CR 9.0 Single Piston

If you're rebuilding the engine in your Acura or Honda with a K20A, K20A2, or K20A3 engine, a strong set of pistons is key to getting it back to spec or even improving performance. This single forged piston from CP Pistons is built to handle the demands of a performance rebuild, offering a solid foundation for your engine's top end.

This piston features an 89mm bore size, which is a +2.0mm overbore compared to stock. It's designed with a 9.0:1 compression ratio, a common target for naturally aspirated builds or those using forced induction where you want to control boost levels. CP Pistons are well-known for their forged construction, which means they are significantly stronger and more durable than cast pistons, making them a popular choice for anyone looking to build a reliable performance engine. This piston is sold individually, so you'll need to order one for each cylinder you're replacing.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
