The CP-Carrillo SC71471XA forged piston set is engineered for high-performance applications in Acura and Honda K24 engines, specifically those paired with K20A/A2 cylinder heads. This set is designed for a 3.445" (87.5mm) bore, with a 99mm stroke, 152mm rod length, and a 1.181" compression height, resulting in a 12.5:1 compression ratio. Constructed from durable 2618 forged aluminum, these pistons feature a dome-type design and are built to withstand the demands of performance engines. The set includes four pistons, complete with rings and wrist pins. CP-Carrillo emphasizes extensive research and development, supporting their parts with input from motorsports professionals, ensuring compatibility with oversized valves and high-lift camshafts. It is explicitly mentioned as fitting 2002-2011 Honda Civic Si models with K24A1, K24A2, and K24Z1 engines. Additionally, some listings specify fitment for K24 engine blocks paired with K20 cylinder heads, and K-Series K24/K20 applications. Note that some sources indicate this product may not be CARB legal.
