Wiseco BMW N54B30 85.00mm Bore 1.244 Compression Height Piston Kit

This kit gets you a set of six forged pistons, specifically made for the BMW N54B30 engine. These pistons are built with an 85.00mm bore and a 1.244-inch compression height, crucial dimensions for rebuilding or upgrading your engine's top end. If you're pushing your N54 hard, whether for track days or serious street performance, these pistons are designed to handle the extra stress.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, which is important when dealing with the higher pressures and temperatures found in performance engines. They feature precision-machined ring grooves, an anti-detonation groove, and other features aimed at improving ring seal for better combustion efficiency and durability. The piston crowns are also fully machined, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated under demanding conditions. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure.

These are intended for heavy to severe duty performance applications, meaning they're built to withstand the rigors of racing and high-output street use. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines.
