For following BMW E46 M3 engines with engine code S54B32.
To maximize power output, the clearances between the rings and piston have been brought in very tightly to reduce blow by. This is achieved by hard anodizing the top ring lands, which prevents micro welding which could be caused otherwise.
To maintain OEM-like wear characteristics, these pistons are coated with Mahle’s Grafal skirt coating. This coating reduces friction on the skirts, keeping them quiet and from wearing over time- extending piston life. The grey appearance of these pistons is due to a phosphate coating. Providing a lubricant film in the pin bores and ring grooves, this coating is essential for initial startup and break-in of the engine to prevent micro welding and galling. Features like these are what allow these pistons to last for thousands of miles, just like OEM units.
