  • supplied with replacement solenoid and has lower profile than T9351 The T9381 is the latest addition to the DV+ family, and offers all the benefits you’d expect from a DV+: Sharper throttle response Faster boost recovery after gearshift or brief throttle lift Improved boost holding Unrivalled longevity, backed by our Lifetime Warranty The T9351 DV+ has been and remains the workhorse of the DV+ family. By replacing the problematic valve mechanism of the factory electronic diverter whilst re-using the solenoid, the T9351 works brilliantly, keeping the cost low and the benefits high. However, with the T9351 there is an increase in overall height of 11mm, which in some cases can cause clearance issues, for example: 2013.5+ Jetta GLI VW Golf MK8 GTi and R Any MQB platform with an aftermarket intake or IS38 turbo Audi 4.0 TFSI from 2012-2017 Here’s where the T9381 comes in. Featuring a low-profile integrated solenoid, the T9381 is shorter and more compact than even the factory diverter, ensuring it will fit the tightest applications. The T9381 can also be used instead of the T9351 when you’d prefer to replace the entire factory diverter valve rather than re-use the factory solenoid (e.g. if your solenoid is faulty).

SHARPER THROTTLE RESPONSE FASTER BOOST RECOVERY ON GEARSHIFT SOLVES BOOST LEAKING ISSUES BUILT TO LAST European manufacturers are pushing their engines to the limit. Get a DV to match. GFB's DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles. By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-orientated product. 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” 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 bin (like other manufacturer’s “solutions”), the DV+ keeps what works and replaces what doesn’t. It retains the factory solenoid and ECU control to ensure simple installation and reliable operation. 10% faster opening, 50% faster closing than the factory diverter Retains the factory solenoid for seamless integration Replaces plastic valve parts with metal for reliability and strength on stock or modified engines Direct-fit replacement with GFB’s TMS benefits Exclusive “pilot-actuated” valve mechanism for rapid response at high boost FITS: Make Model Mark Variant EngineCodes FuelType YearFrom YearTo Audi A1 8X1 3-Door Hatchback 1.8 TFSI Petrol 2015 2018 Audi A1 8X1 3-Door Hatchback S1 quattro Petrol 2014 2018 Audi A3 MK2 8P1 3-Door Hatchback 1.8 TFSI Petrol 2006 2012 Audi A3 MK2 8P1 3-Door Hatchback 2.0 TFSI Petrol 2004 2012 Audi A3 MK2 8P1 3-Door Hatchback 2.0 TFSI quattro Petrol 2004 2012 Audi A3 MK2 8P1 3-Door Hatchback S3 quattro Petrol 2007 2012 Audi A3 MK2 8P7 Cabriolet 1.8 TFSI Petrol 2008 2013 Audi A3 MK2 8P7 Cabriolet 2.0 TFSI Petrol 2008 2013 Audi A3 MK2 8PA 5-Door Sportback 1.8 TFSI Petrol 2006 2013 Audi A3 MK2 8PA 5-Door Sportback 2.0 TFSI Petrol 2004 2013 Audi A3 MK2 8PA 5-Door Sportback 2.0 TFSI quattro Petrol 2004 2013 Audi A3 MK2 8PA 5-Door Sportback RS3 quattro 2.5 TFSI Petrol 2011 2012 Audi A3 MK2 8PA 5-Door Sportback S3 quattro Petrol 2008 2013 Audi A3 MK3 8V1 3-Door Hatchback 1.8 TFSI Petrol 2012 2024 Audi A3 MK3 8V1 3-Door Hatchback 1.8 TFSI quattro Petrol 2012 2024 Audi A3 MK3 8V1 3-Door Hatchback S3 quattro Petrol 2013 2024 Audi A3 MK3 8V1 3-Door Hatchback S3 quattro Petrol 2014 2024 Audi A3 MK3 8V1 3-Door Hatchback S3 quattro Petrol 2012 2024 Audi A3 MK3 8V1 3-Door Hatchback S3 quattro Petrol 2016 2020
