Kit of two Forge Motorsport atmospheric dump valves for the Audi RS4 B9 and RS5 F5. The kit includes two solenoid-controlled valves and a custom-made wiring harness that connects seamlessly to the vehicle’s original electronics. The system does not cause fault codes or an engine warning light and does not negatively affect the vehicle’s operation.
The valves are designed as a solution to problems with the original solenoid valves, where the diaphragm can rupture and cause boost pressure leaks. They are made entirely from machined aluminium and feature an internal piston design that provides significantly greater reliability than the original valves, as well as a very fast response.
The kit includes:
- 2 dump valves
- O-rings for sealing the valves
- Vacuum hose
- Solenoid valve
- Wiring harness
- Cable ties
- Bracket and mounting hardware
- Upgraded springs – one for each valve
Suitable for: Audi RS4 V (B9), Audi RS5 II (F5).
