CP Piston & Ring Honda/Acura B16A - Bore (81.mm) - CR (10.5:1) (Single Piston)

CP Pistons is well-known for making strong, reliable internal engine components for performance applications. This single forged piston, part number SC7100-1, is built for Honda and Acura B16A engines. It features an 81.0mm bore and a 10.5:1 compression ratio, making it a solid choice for engine rebuilds where improved performance is the goal.

Forged pistons like this one are made from a solid block of aluminum that's heated and hammered into shape under extreme pressure. This process creates a much denser, stronger grain structure than cast pistons, which means they can handle higher cylinder pressures and temperatures without deforming or failing. This makes them ideal for boosted applications or high-performance naturally aspirated builds. The included piston rings are designed to work with this specific piston, ensuring a good seal in the cylinder bore.

When rebuilding your B16A engine, choosing the right piston is critical for both durability and performance. This CP Piston offers a well-built option with a specific compression ratio that can be tailored to your build's needs. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and ring gap setting.
