Wiseco BMW M50B25 84.25 mm Bore 38.20 mm CH -1.50 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your BMW M50B25 engine. The 84.25 mm bore size is a specific measurement that matters when you're rebuilding or modifying your engine for more power. This set is designed for heavy to severe duty applications, meaning they're made to handle the stress of high-performance driving and racing builds.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and extra ring seal improvements. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures a clean combustion chamber, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. This is a set of six pistons, ready for your next engine project.

Because these are designed for demanding builds, it's important to note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
