CP Piston & Ring Set for Honda K20A/A2 - Bore 86.mm - STD Size - Compression Ratio 11.5

CP Pistons is well-known for making strong internal engine components, and this piston and ring set is a prime example for your 2002-2004 Acura RSX. If you're rebuilding the engine in your RSX, especially if you're looking to improve performance or handle more power, a set of forged pistons like these is a critical part of the job. They are designed to handle the increased stress and heat that comes with higher compression ratios and more aggressive engine tuning.

This set is specifically made for the Honda K20A and K20A2 engines, featuring a standard bore size of 86.0mm. The pistons are forged, which means 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 ones, making them ideal for high-performance applications. They come with a compression ratio of 11.5:1, which is a notable increase over stock and will contribute to improved power output when paired with the right supporting modifications and tuning. The set includes the pistons and the necessary rings to get them installed.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and torque specifications to ensure proper function and longevity. Because these are a performance part with a higher compression ratio, they are not CARB approved and cannot be shipped to California. Make sure to consult your engine builder or a trusted mechanic to confirm all necessary supporting modifications and tuning requirements for your specific build.
