Wiseco BMW M50B25 Single Vanos 2.5L 24V Turbo 85.0mm Bore 1.00 Over Size 8.8:1 CR Piston Set

If you're building a high-performance turbo M50B25 engine for your BMW, this set of Wiseco forged pistons is a solid choice. These pistons are specifically made for the M50B25 Single Vanos 2.5L 24V engine, with an 85.0mm bore and a compression ratio of 8.8:1, designed to handle turbocharging and heavy-duty use.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding applications. They feature precision ring grooves, anti-detonation grooves, and other features to enhance ring seal, ensuring reliable performance under boost. The piston crowns are fully machined, and they include forced pin oiling for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making them well-suited for severe duty builds.

This set includes six pistons, each with a 32.70mm compression height and an 0.866 inch pin diameter. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, these Wiseco pistons offer a strong foundation.
