Our most frequently asked questions
- What about the neighbors in the morning? The valves are controlled as on the factory system: closed and discreet at startup or in comfort mode, fully open in sport mode.
- Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the contrôle technique.
- Fitting: the system uses the original mounting points. A repair shop with the right equipment typically fits it in one to two hours.
Why choose Milltek Sport?
