The original valves are not fully sealed from the factory, causing a loss of performance. This loss is even more noticeable in tuned vehicles because of the higher boost pressure. Fitting the GFB DV+/VTA closes this »gap« in the charge-air system, noticeably improving throttle response and boost retention. The turbocharger is also protected because it no longer has to work »against« a leak in the charge-air system.
At the same time, the familiar »whoosh« sound is produced during gear changes by venting excess charge air to the atmosphere. Other manufacturers offer a simple spacer to create a Blow Off sound, fitted beneath the original valve. Although it produces a Blow Off sound, it does not solve the problem of the leaking original valve. The GFB VTA valve eliminates both problems at once.
The GFB T9480 is suitable for all 2.0 EA888 evo4 and 3.0 TFSI engines.
