CP Piston & Ring Set for Honda F22C - Bore (87.5mm) - Size (+0.5mm) - Compression Ratio (9.0)

CP Pistons is well-known for making strong, reliable internal engine components, especially for performance applications. This piston and ring set is built for the 2004-2009 Honda S2000, specifically for the F22C engine. If you're rebuilding the top end of your S2000, perhaps after a rebuild or looking to tune for more power, a fresh set of pistons is a critical part of the job. This set is designed to fit right into your F22C block, but it's important to note these are a +0.5mm oversize, meaning your cylinders will need to be bored to 87.5mm to match.

These are forged pistons, which means they are made from a solid block of aluminum that's heated and hammered into shape. This process makes them significantly stronger and more durable than cast pistons, which is essential if you plan on pushing your engine harder than stock. The compression ratio for this set is 9.0:1, which is a common target for naturally aspirated builds or mild forced induction setups. This specific set includes the pistons and the rings needed to complete the installation, ensuring you have the core components ready for your engine build.

When installing these pistons, remember that they are an oversize part. You'll need to ensure your engine builder or machine shop has accurately bored and honed your cylinders to the specified 87.5mm bore size. Proper cylinder wall preparation is key to the longevity and performance of these components. Please be aware that this part is not CARB approved and cannot be shipped to California.
