CP Piston & Ring Set Honda/Acura K24 w/K20A/A2 - Bore 88mm +1.0mm Oversized 12.5 CR

This is a set of forged pistons and rings from CP Pistons, specifically made for Honda and Acura K24 engines that are also running K20A or K20A2 cylinder heads. These pistons are designed to be 88mm in bore diameter, which is 1.0mm oversized from the stock dimension, and they feature a 12.5:1 compression ratio. If you're rebuilding the top end of a performance-oriented K-series engine, these pistons are a solid foundation for increased power and durability.

CP Pistons are well-known in the performance world for their robust construction. These are forged from high-strength aluminum alloy, which is much stronger and more resistant to detonation than cast aluminum. This strength is crucial when you're pushing an engine beyond its original limits, especially with a higher compression ratio like 12.5:1. The pistons are machined to precise tolerances, ensuring a good seal with the cylinder walls and the included rings. The 1.0mm oversized bore means these are intended for engines that have already been bored out to accommodate them, typically during a performance rebuild where the cylinders might have some wear or need to be enlarged for better airflow. The 12.5:1 compression ratio is a significant bump over stock, designed to work with performance camshafts and tuning to extract more power from the engine.

When installing these pistons, remember they are oversized and require a properly bored and honed engine block. It's also essential to ensure your K20A/A2 cylinder head is compatible with the K24 block and that your engine management system is tuned to take advantage of the increased compression and airflow. This set includes the pistons and the necessary rings to complete the installation. Please note that this part is not CARB approved and cannot be shipped to California.
