About this part

Product Details

CP Pistons is known for making strong, well-built internal engine components. This forged piston, part number SC7136-1, is designed for the Acura B18C5 engine. It features a bore size of 81.5mm and a compression ratio of 11.5:1, making it a solid choice for builds looking to improve performance over stock.

Forged pistons like this one are built from a solid block of aluminum that's heated and hammered into shape, which makes them significantly stronger and more durable than cast pistons. This increased strength is crucial for handling the higher cylinder pressures and temperatures found in modified or performance-oriented engines. The 11.5:1 compression ratio is a notable increase over many factory setups, which can lead to improved power output when paired with appropriate tuning and supporting modifications.

This piston is sold individually, so be sure to order the correct quantity for your engine. It's important to note that this part is not CARB approved and cannot be shipped to California.
