2.5 TFSI EA855 upgrade pop off valve GFB DV+

The most desirable pop off valve on the market from GFB. Unfortunately, the original boost air valves are very susceptible and will all leak, causing a loss of power, which is even more noticeable on performance cars due to the higher boost pressure. You don't notice the loss of boost pressure at first, as the diaphragm gradually tears. The GFB valve is the best solution to prevent the loss of boost pressure! The GFB valve comes 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! Note: On the RS3 8P model, the line of the transmission oil cooler must be slightly offset so that it fits!
