Product Details

Forged from high-strength aluminum alloy, these CP Pistons SC7045-4 piston and ring sets are built for the demands of high-performance K-series engines found in the 2002-2006 Acura RSX. Specifically designed for K24 blocks utilizing K20A, A2, or A3 cylinder heads, this set features a standard 87mm bore size, ensuring a precise fit for your engine rebuild. The advanced forging process creates a piston that is both lightweight and incredibly strong, capable of handling increased cylinder pressures and temperatures common in modified applications.

CP Pistons is well-known for its commitment to precision and durability. Each piston in this set is meticulously machined to exact tolerances, contributing to improved sealing and optimal combustion efficiency. The included rings are also selected to complement the piston's design, helping to maintain proper oil control and compression. This set is a solid option for anyone looking to rebuild or significantly upgrade their K-series engine, whether for track use or spirited street driving. Remember, these pistons are designed for a standard bore, making them a direct replacement for stock-sized bores or a perfect starting point for a hone and re-ring job.

When undertaking an engine build of this caliber, it's crucial to ensure all components are installed correctly according to manufacturer specifications. While this set includes the pistons and rings, you will need to source other necessary components for a complete engine rebuild, such as bearings, gaskets, and potentially an oil pump upgrade, depending on your specific build goals. Please note that this part is not CARB approved and cannot be shipped to California.
