CP Pistons are well-known for their robust construction, and this forged piston is built to handle the demands of performance applications. Forging the aluminum creates a stronger, more durable piston compared to cast designs, which is crucial for engines that see spirited driving or track use. The 86.50mm bore with the +0.5mm oversize is specific for engines that may have already been honed or require a slightly larger piston to achieve proper cylinder wall clearance. The 9.0:1 compression ratio is a popular choice, offering a good balance between power output and drivability for many RB25DET builds.

Please note that this piston is not CARB approved and cannot be shipped to California. Always consult with your engine builder or a qualified mechanic to ensure this piston is the correct component for your specific engine build and performance goals.
