Official Release:

Now MAHLE Motorsport provides a budget minded option to replace OE cast pistons standard with the B50 or S85 engine with their all forged PowerPak piston kit designed for the 5.0: V10 B50 or S85 BMW engine. Manufactured from 4032 aluminum alloy for high temperature strength and low noise, the pistons are dual coated with MAHLE’s dry lubricant Phosphate coating and a proprietary Gold skirt coating (GRAFAL) for reduced wear and drag.
