Upgraded piston type design, modeled after the more robust aftermarket diverter valves. The old diverter valve 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 wants to upgrade their car with a stronger OEM diverter valve.
