One of the things that hot rodders of generations past could likely never conceive of is the amount of technology involved in the creation of modern pistons. With the ever advancing science and engineering of engine building, the ever greater stresses being placed on the pistons, and the ever higher expectations of end users, things like piston coatings become really, really important. In this video the guys from MAHLE tell us about the gold series coating that is available on their pistons and the technology behind said coatings and what their intended applications and benefits are.
All MAHLE pistons come with a Phosphate coating that gives the pistons their signature grey appearance but the gold series coating is an entirely new step in the process an it utilizes the latest in coating technology to help your engine gain in power, reliability, and durability. It is mind boggling to think that substances that are measured in microns can make this much different in the way your engine works!
