GFB DVX Diverter Blow Off Valve | MK7 R · 8V S3 · MK3 TTS · MK1 Arteon | 2.0L Turbo I4

GFB’s DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to “pilot actuation” (read about this below) to ensure better performance on stock or modified engines. Furthermore, these benefits won’t cost you the Earth! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer’s “solutions”), the DV+ keeps what works, and replaces what doesn’t. There are many “BOV spacers” on the market that make noise. However, they do this simply by using the factory diverter valve and redirecting the air to atmosphere. Therefore, the performance deficiencies of the factory diverter valve design remain, and furthermore, the flow capacity of the factory diverter is significantly reduced because of the small venting holes used in these BOV spacers. Other BOV kits eliminate the ECU control entirely, using pure manifold vacuum control instead. Whilst there’s nothing particularly
