Genuine Pierburg OEM diverter valve. Features the upgraded piston type design, modeled after the more robust aftermarket diverter valves. The old DV is prone to failure, regardless of if your car is stock or chipped, as the fragile diaphragm can rupture under boost pressure, resulting in a boost leak that will hinder your car's performance. This is the ideal solution for anyone who want to upgrade their car with a stronger OEM diverter valve. Made in Germany by Peirburg.
