JE Pistons PORSCHE 3.8L DM KIT Set of 6 Pistons

If you're working on the engine of your 2004 Porsche 911 and need a set of pistons that can handle serious performance, JE Pistons has you covered. This is a complete set of six forged pistons designed specifically for the 3.8L engine, giving you the foundation for a robust build.

JE Pistons has been making forged pistons for over 75 years, and they build these right here in the USA from 2618 aluminum. This material is chosen because it has the high tensile strength needed for demanding performance applications. They use a proprietary Forged Side Relief (FSR) design, which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons might also feature an accumulator groove to help control combustion gas pressure, leading to better ring seal and consistent power. Plus, some applications include a skirt coating to further reduce friction and noise.

This kit comes with everything you need to get your pistons installed: the six pistons themselves, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Just remember, these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
