CP Piston & Ring Set for Honda F22C - Bore (87mm) - Size (STD) - Compression Ratio (11.0)

CP Pistons is well-known for making strong, reliable internal engine components, and this piston and ring set for the 2004-2009 Honda S2000 is a prime example. If you're rebuilding the heart of your S2000, especially if you're looking to improve performance or replace worn-out parts, this set is built to handle the demands of the F22C engine.

This set features pistons with a standard 87mm bore, meaning they're designed to fit precisely into a factory-spec cylinder bore. The compression ratio is set at 11.0:1, which is a common target for builds that aim for a noticeable bump in power without going too extreme, offering a good balance between performance and pump gas compatibility. These are forged pistons, which means they start from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them more resistant to the high pressures and temperatures found in a performance engine. This strength is crucial for longevity, especially if your S2000 sees track time or aggressive driving.

Included with the pistons are the necessary rings to complete the assembly. Proper ring installation is key to sealing the combustion chamber and managing oil, so make sure to follow the manufacturer's instructions carefully. Please note that this part is not CARB approved and cannot be shipped to California. If you're looking for a well-built set of pistons to form the foundation of your S2000's engine build, this CP Pistons set is a solid option.
