Mahle MS BMW N54 B30 3.0L 84.00mm x 31.7mm CH 17.2cc 314g 10.2CR Pistons (Set of 6)

If you're rebuilding the engine in your BMW N54 3.0L, especially if you're looking to improve performance or handle more power, a set of high-strength forged pistons like these from Mahle is a critical component. These pistons are designed to replace the factory ones and are built to withstand the increased stresses of a performance-oriented build. The N54 engine is known for its potential, and upgrading the pistons is a common step when pushing its limits.

Mahle crafted these pistons from a strong 2618 aluminum alloy, a material chosen for its excellent thermal properties and durability under high loads. Each piston measures 84.00mm in bore diameter, with a compression height (CH) of 31.7mm. The dish volume is -17.2cc, which, combined with the other engine dimensions, results in a 10.2:1 compression ratio. This ratio is suitable for many performance applications, offering a good balance between power and drivability. Each piston weighs in at 314g, helping to keep the rotating assembly balanced.

This set includes six pistons, enough for a complete engine rebuild. It's important to note that these pistons are not CARB approved and cannot be shipped to California. When installing these, ensure you follow the manufacturer's detailed installation instructions, paying close attention to ring gap, piston-to-wall clearance, and proper lubrication. A balanced rotating assembly and proper engine tuning are essential for optimal performance and longevity with these upgraded components.
