What material are these pistons made from?

These pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to perform under high-stress conditions common in performance engines.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to optimize the piston's movement within the cylinder. This helps to reduce friction and wear on the cylinder walls while still allowing the piston to generate substantial power.

Are these pistons compatible with all N54B30 engines?

This piston set is designed for the BMW N54B30 engine with an 84.5mm bore and a 32cc dish. It is crucial to confirm that these specifications match your engine's requirements and your desired compression ratio. They are not CARB approved and cannot ship to California.
