Sport Compact, Import and European forged pistons from JE Pistons are the result of over 75 years of industry leading experience extended to our range of premium forged pistons for BMW S50B30 Euro Engines. JE Pistons are designed for each specific engine and racing application to provide the ultimate combination of durability and performance. From drift track to drag strip, JE Pistons’ performance is proven in victory lane time and time again. Equipped with the following custom level features

• Accumulator Groove: A specialty groove between the top and second ring provides added volume for blow-by gases. This helps reduce pressure between the rings, improving top ring seal and minimizing ring flutter at high cylinder pressures.
• Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
• Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
• Skirt Coat: Skirt Coat reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
