CP Piston & Ring Set for Honda K24 w/K20A/A2 - Bore 90.0mm - Size (+3.0mm) - Compression Ratio 11.5

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

These pistons are forged from high-strength aluminum, a process that creates a denser, more robust material compared to cast pistons. This makes them much more resistant to the extreme pressures and temperatures found in a high-performance engine. This particular set features a 90.0mm bore, which is 3.0mm larger than stock, meaning it's intended for engines that have already been bored out to accommodate this size. The compression ratio is set at 11.5:1, which is a notable increase over stock and will contribute to improved power output when paired with appropriate tuning and supporting modifications. The set includes the pistons and the necessary rings to complete the installation.

When installing these pistons, ensure your engine block has been professionally bored and honed to the exact 90.0mm specification to ensure a proper seal and optimal performance. It's also crucial to follow the manufacturer's recommended clearances and lubrication procedures. Remember that this part is not CARB approved and cannot be shipped to California.
