Product Details

Forged from 2618 aluminum alloy, these Mahle MS pistons are built for the demanding N54 3.0L engine. With a bore of 84.50mm and a compression ratio of 10.3:1, they are designed to handle increased cylinder pressures and temperatures that come with performance builds or engine rebuilds. The 31.7mm compression height and 22mm pin diameter are specific to the N54 application, ensuring proper fitment within the engine's geometry.

Mahle's forging process creates a stronger, more durable piston than cast alternatives, making them a solid choice for enthusiasts looking to push their N54 beyond stock performance levels. Each piston weighs in at approximately 320g, and the set includes six pistons, along with the necessary components for installation. These pistons are engineered to work with the N54's 89.6mm stroke and 145.05mm connecting rods, maintaining the correct piston-to-valve clearance and deck height.

When rebuilding or modifying your N54 engine, choosing well-built internal components like these Mahle pistons is crucial for reliability and performance. Remember 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.
