CP Piston & Ring Set for Honda K20A/A2 - Bore 86.5mm - Size (+0.5mm) - Compression Ratio 11.5

This product is a set of four forged pistons and matching rings for your 2002-2004 Acura RSX with a K20A or K20A2 engine. These pistons are designed to be 86.5mm in bore diameter and are 0.5mm oversize, intended for engines that may have been bored out during a rebuild. They feature an 11.5:1 compression ratio, which is a notable increase over stock, meaning you'll get more power out of each combustion cycle.

CP Pistons is known for making well-built engine components, and these pistons are no exception. They are forged from high-strength aluminum alloy, a process that makes them significantly stronger and more durable than cast pistons. This strength is crucial for handling the increased cylinder pressures that come with a higher compression ratio and for performance applications. The included rings are designed to seal the combustion chamber effectively, ensuring optimal compression and oil control.

When rebuilding or modifying your K20A/A2 engine, choosing the right pistons is key. These CP Pistons are a solid option if you're looking to increase your engine's performance and durability. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
