JE Pistons Ferrari 4.0L 330 V12 2V - 78.00 mm Bore - 1.173 in. CH, 15.00 CC - Set of 12

When you're rebuilding the heart of a classic Ferrari 4.0L 330 V12, especially for high-demand performance applications, the pistons are critical. JE Pistons has been a leader in forged racing pistons for over 75 years, and this set of 12 is built to meet those demanding standards. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when pushing an engine to its limits.

These aren't just generic pistons; they're designed specifically for the Ferrari 330 V12 engine. You'll find JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on the specific application, you might also get an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear, which can also quiet down engine noise.

This set includes everything you need to get your V12 back in top shape: the 12 pistons themselves, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. They are made 100% in the USA, ensuring you're getting a well-built component for your prized Ferrari. Please note that these pistons are not CARB approved and cannot be shipped to California.
