BMW F20, F21, F30, Dodge Dart, Fiat Abarth upgrade pop off valve GFB

The most desirable pop off valve on the market from GFB. Unfortunately, the original divert-air valves are very susceptible and all leak, causing a loss of power that is even more noticeable in performance-enhanced vehicles due to the higher boost pressure. You don't notice the loss of boost pressure at first, as the diaphragm creeps in. The GFB valve is the best solution to prevent the loss of boost pressure! The GFB valve is supplied as a complete kit and replaces the faulty part of the original valve. So there is no need to buy a new pop off valve from VW or Audi!
