Carrillo BF9823-030-8 Ford 4.6L 4V Power Adder Forged Piston & Ring Set

The Carrillo (CP-Carrillo) BF9823-030-8 is a complete forged piston and ring set engineered for the Ford 4.6L 4-valve Modular engine in power adder applications. Designed specifically to handle the extreme cylinder pressures generated by nitrous oxide, supercharger, and turbocharger setups, these pistons deliver the strength and precision required for high-performance forced induction builds.

Each piston is precision-forged in the USA from 2618 aluminum alloy, a material known for its superior fatigue resistance and toughness under thermal and mechanical stress — making it the preferred choice for power adder builds over cast or hypereutectic alternatives.
