Wiseco BMW M50B25 -1.50cc Dome 85.00 mm Bore 38.20 mm CH Piston Kit (Set of 6)

If you're rebuilding the engine in your BMW M50B25, this set of six forged pistons from Wiseco is built for serious performance. These aren't your average pistons; they're designed for heavy-duty race applications where durability and consistent performance under extreme conditions are critical. Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for handling the high pressures and temperatures found in a performance engine build.

You'll find precision machining throughout, including the crown, anti-detonation grooves, and features that enhance ring seal. The ArmorGlide skirt coating is a notable addition, helping to reduce friction, resist seizure, and contribute to quieter operation. This coating is especially important in high-performance engines where piston-to-wall clearance is tight and heat management is key. The forced pin oiling system ensures the wrist pin receives adequate lubrication, further enhancing longevity in demanding builds.

This kit includes everything needed for a six-cylinder engine, with each piston featuring an 85.00 mm bore and a 1.50 cc dome. Remember that these pistons are not CARB approved and cannot be shipped to California. For a robust engine rebuild, these Wiseco pistons offer a well-built foundation.
