CP Piston & Ring Set for Acura/Honda K24 w/K20A/A2/A3 - Bore (89.0mm) - Size (+2.0mm) - Compression

CP Pistons is well-known for making strong internal engine components, and this piston and ring set is a prime example of their work for performance builds. If you're working on a 2002-2006 Acura RSX and looking to upgrade your engine's internals, this set is designed to handle the demands of a modified K-series engine.

This set features pistons with an 89.0mm bore and a +2.0mm oversize, meaning they are intended for engines that have already been bored out to accommodate larger pistons. They are forged from high-strength aluminum, a common material for performance pistons because it offers a good balance of strength and weight. This construction helps them withstand higher cylinder pressures and temperatures compared to cast pistons, making them suitable for builds aiming for increased horsepower or more aggressive tuning. The set includes the necessary rings, which are crucial for proper sealing between the piston and cylinder wall, ensuring optimal compression and oil control.

When installing these pistons, remember they are an oversize part, so the engine block will need to be machined to the correct 89.0mm bore size by a qualified machine shop. This ensures a precise fit and proper clearance for reliable operation. This set is not CARB approved and cannot be shipped to California.
