CP Piston & Ring Set for Honda F22C - Bore (87.5mm) - Size (+0.5mm) - Compression Ratio (11.0)

This is a CP Pistons SC7171-4 piston and ring set specifically for the 2004-2009 Honda S2000 with the F22C engine. If you're rebuilding the top end of your S2000's engine, especially if you're looking to increase displacement or handle more power, a set of forged pistons like these is a critical component. They are designed to be a direct replacement for your stock pistons, but with improved strength and durability for performance applications.

These pistons are forged from high-strength aluminum, a process that makes them significantly stronger and more resistant to detonation and fatigue compared to cast pistons. This particular set is sized at 87.5mm, which is a +0.5mm overbore from the factory specification, allowing for a slight increase in displacement. They feature a compression ratio of 11.0:1, which is a common target for naturally aspirated or mildly boosted builds, offering a good balance between power and drivability. The set includes the pistons and the necessary rings to complete the installation.

When rebuilding an engine, especially one with a higher performance goal, using well-built internal components is essential. These CP Pistons are a popular choice for S2000 owners looking for reliable performance. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
