Wiseco BMW M50B25 2.5L Engine 11:1 CR 84.5MM Bore Custom Pistons (Set of 6)

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This set of six custom pistons is built for the BMW M50B25 2.5L engine, featuring an 11:1 compression ratio and an 84.5mm bore. These aren't your average pistons; they're designed for serious racers and builders who demand durability and performance under heavy or severe duty conditions.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the extreme pressures inside a performance engine. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, quiet operation, and resist seizure. The fully machined crown and forced pin oiling further contribute to their robust design, ensuring they can handle demanding race builds.

This set includes everything needed to outfit your M50B25 engine with these custom pistons. Remember that these pistons are not CARB approved and cannot be shipped to California. For optimal installation, always refer to the manufacturer's detailed instructions.
