CP Piston & Ring Set for Acura/Honda K24 w/K20A/A2/A3 - Bore (86mm) - Size (STD) - Compression Ratio

Starting with a standard bore size of 86mm, this CP Pistons set is built for the 2002-2006 Acura RSX, specifically for K24 engines utilizing K20A, A2, or A3 cylinder heads. These aren't your typical cast pistons; they are forged from high-strength aluminum alloy, a crucial choice for engines that see higher performance demands. Forging makes the pistons significantly stronger and more resistant to the extreme pressures and temperatures generated during combustion, which is essential when you're pushing an engine beyond its factory limits.

The design of these pistons contributes to improved engine performance by optimizing the combustion chamber. CP Pistons carefully engineers the crown shape to work with specific cylinder head designs, aiming for efficient burn and reliable power delivery. This set includes the necessary rings, which are also selected to complement the piston's performance characteristics, ensuring a good seal between the piston and cylinder wall. A proper seal is vital for maintaining compression, controlling oil consumption, and maximizing the engine's output. The standard bore size means these pistons are intended for engines that haven't been bored out, making them a direct replacement for stock dimensions or for builds where the block is being refreshed to its original specifications.

When undertaking an engine build or rebuild that involves these pistons, it's important to follow the manufacturer's detailed installation instructions. Proper ring gapping, piston-to-wall clearance, and lubrication are critical for the longevity and performance of the engine. This set is a solid option for enthusiasts looking to build a more robust and capable K-series engine for their RSX.
