CP Piston & Ring Set for Acura/Honda K20A/A2/A3 - Bore (88mm) - Size (+2.0mm) - Compression Ratio (F

What you get in this box is a set of four forged pistons and their matching ring sets, all ready to go into your 2002-2006 Acura RSX. These are specifically made for the K20A, K20A2, and K20A3 engine families, which means they're built to handle the demands of a performance-oriented build. The pistons themselves are 88mm in bore size and are an oversize set, meaning they are 2.0mm larger than stock. This is a common choice when rebuilding an engine to restore its original bore or to increase displacement slightly.

CP Pistons is known for making well-built engine components, and these pistons are no exception. They're forged from high-strength aluminum, which gives them a solid foundation for higher compression or boosted applications. The fact that they're an oversize set means they're designed to be used in an engine block that has already been bored out to match this 88mm dimension. This is a critical step for engine builders looking to refresh worn cylinders or achieve a specific displacement target. The included ring sets are matched to the pistons, ensuring a proper seal when installed.

When you're rebuilding the top end of your K-series engine, especially if you're aiming for more power or need to address significant wear, a set of quality forged pistons like these is a smart move. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for precise details on fitting these pistons into your specific engine build.
