Product Details

These Mahle forged pistons are built with 2618 aluminum, a strong material commonly used in high-performance applications because it handles the heat and pressure of boosted engines well. Each piston measures 82.00mm in bore diameter and features a 33.27mm compression height, which is crucial for achieving the correct valve-to-piston clearance and compression ratio. They are designed for a 94.6mm stroke and a 148.2mm rod length, with a 22mm wrist pin diameter. The -11.0cc dish volume contributes to a 10.6:1 compression ratio when paired with the correct cylinder head and gasket combination, offering an improved performance feel over stock without being excessively aggressive for daily driving.

Weighing in at 299g each, these pistons are a well-built replacement for your BMW B58 3.0L engine. Mahle is a well-known name in engine components, and these pistons reflect their commitment to producing reliable parts for demanding builds. The 2618 aluminum alloy offers good thermal expansion properties, helping to prevent piston slap when cold and maintain a solid seal when hot. This set includes six pistons, enough for a complete engine rebuild. Remember that these pistons are not CARB approved and cannot be shipped to California.
