CP Piston & Ring Set for Honda K24 w/K20A/A2 - Bore 87.5mm - Size (+0.5mm) - Compression Ratio 11.5

CP Pistons is well-known for making strong, reliable internal engine components. This piston and ring set is built for the 2002-2004 Acura RSX, specifically for Honda K24 engines when paired with K20A or K20A2 cylinder heads. If you're rebuilding the top end of your engine and looking for a solid upgrade, this set is designed to handle increased performance demands.

This set features pistons with an 87.5mm bore, which is a +0.5mm overbore compared to stock. This is often done to clean up cylinder walls or achieve a specific displacement. The compression ratio comes in at 11.5:1, a notable bump over stock that will increase power output, especially when paired with appropriate tuning and supporting modifications. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for higher performance applications where heat and pressure are greater.

When installing these, remember they are an overbore size, so ensure your engine block is properly machined to the correct 87.5mm bore diameter. The set includes the pistons and the necessary rings to complete the assembly. Please note that this part is not CARB approved and cannot be shipped to California.
