We recommend servicing the valve every 3 years or every 20,000 miles – whichever comes first.
Aluminium flange-mounted recirculation ram dump valve designed for Impreza V5. The recirculation diverter valve is made from billet aluminium and returns charge air to the intake system, keeping external noise to a minimum. It enables faster throttle response and provides greater clamping force for more reliable boost pressure retention.
The kit includes:
- 1 × FMDVV5013 valve
- 1 × Forge sticker
The valve operation can be adjusted to suit the engine’s requirements with an adjustment spring kit.
Suitable for: Subaru Impreza I (GC/GF).
