Wiseco BMW M54B30 -7.3cc Dish 1.1937in x 3.3169in

If you're rebuilding the engine in your BMW M54B30 for serious performance, a strong set of pistons is where you start. These Wiseco Professional Series pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of heavy to severe duty race builds. They are precision machined right here in the USA to ensure they meet the high standards required for performance engine work.

Wiseco has packed these pistons with features to enhance both durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The piston crown is fully machined for a clean, consistent surface, and they incorporate forced pin oiling to keep the wrist pins lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life.

This set includes six pistons, each with a -7.3cc dish volume and a bore size of 84.25mm. The compression height is 30.32mm, and they use a 0.8661-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
