JE Pistons BMW S50B30 FSR KIT - Set of 6 Pistons

This kit gives you a complete set of six JE Pistons, designed specifically for the BMW S50B30 Euro engine. These aren't just any pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushed hard in performance applications. JE Pistons has been doing this for over 75 years, and they build these pistons right here in the USA, applying that experience to every set.

What sets these pistons apart is JE's proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and power loss by using a narrower skirt and a shorter wrist pin, which also helps save weight. Depending on your specific engine setup, you might also get an accumulator groove to help control combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating that cuts down on friction and wear against the cylinder walls, making things run quieter and smoother while also reducing wear.

This kit comes with everything you need to get these pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. They are engineered specifically for the S50B30 engine and its intended use, aiming for the best balance of performance and durability. Just remember, these pistons are not CARB approved and cannot be shipped to California.
