Product Details

If you're rebuilding the engine in your BMW N54 3.0L, getting the right pistons is crucial for performance and reliability. This Mahle MS piston is built for that job, offering a solid foundation for your build. It's designed with a 10.2:1 compression ratio, which is a common and effective target for many N54 builds looking for a bit more power without sacrificing too much drivability.

This piston is forged from 2618 aluminum, a strong material often used in performance applications because it can handle the heat and stress of a high-output engine. It measures 84.00mm in bore diameter with a 31.7mm compression height, and it weighs in at 314 grams. The dish volume is -17.2cc, contributing to that 10.2:1 compression ratio when paired with the correct cylinder head and gasket combination. Remember, this is a single piston, so you'll need to order the correct quantity for your engine.

Please note that this part is not CARB approved and cannot be shipped to California. Always refer to your specific engine build plans and manufacturer instructions for proper installation and compatibility.
