Wiseco BMW M50B25 2.5L 24V Turbo 84.00MM Bore STD Size 8.8:1 CR Pistons

If you're building a serious performance engine for your 1991-1995 BMW 525i, this set of six Wiseco forged pistons is what you'll want. These are designed for the M50B25 2.5L 24V engine and come with an 84.00mm bore size and a standard 8.8:1 compression ratio, making them a solid choice for turbo builds that need to handle significant stress.

Wiseco makes these pistons in the USA from 2618 aluminum, which gives them improved tensile strength for demanding applications. You'll find precision ring grooves, anti-detonation grooves, and features that help seal the rings even better, all contributing to improved performance and durability. The piston crown is fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure.

This set includes everything you need to outfit your engine with these well-built pistons, including the pistons themselves and premium rings. Keep in mind these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
