PowerPak Features:

** Phosphate coating provides the grey appearance to the MAHLE piston. This dry lubricant coating (not to be confused with a thermal film coating) provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and microwelding. The piston crown is still machineable.

Please Note: All engine modifications should be performed by a qualified professional to ensure a proper and safe installation process and a reliable, optimally performing engine.
