Mahle MS forged pistons for the BMW N54 3.0L engine. This set includes six pistons, each measuring 84.50mm in bore diameter with a 31.7mm compression height. These pistons are designed to handle the demands of a performance-oriented N54 build, offering a solid foundation for engine rebuilding or upgrades. The 9.6:1 compression ratio is suitable for naturally aspirated or boosted applications where a balance between power and drivability is desired.

Crafted from durable 2618 aluminum, these pistons are built for strength and reliability under high stress. The -21.5cc dish volume contributes to the 9.6:1 compression ratio when paired with the N54's stock 89.6mm stroke and 145.05mm connecting rod length. Each piston weighs 314g, contributing to a well-balanced rotating assembly for smoother engine operation and improved performance. The 22mm pin size is standard for many performance applications.

This set is a popular choice for enthusiasts rebuilding or modifying their N54 engines. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures, especially when dealing with critical engine components like pistons.
