Wiseco BMW M54B30 3.0L 24V 84.5mm Bore -7.3cm Dish 9.0:1 CR Pistons - Set of 6

When you're rebuilding the top end of your BMW M54B30 engine, this set of six forged pistons from Wiseco is what you'll get. Each piston has an 84.5mm bore and a dish volume of -7.3cc, resulting in a 9.0:1 compression ratio. These are built for serious performance applications, designed to handle the stress of heavy to severe duty use.

Wiseco makes these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength. They feature precision ring grooves, an anti-detonation groove, and other features to help seal the rings better. The piston crowns are fully machined, and they also come with forced pin oiling to keep things lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set includes the pistons, rings, and pins needed for your rebuild. Keep in mind 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.
