Milltek Active Valve Control Bluetooth Module

This neat little plug n play device from Milltek allows you to control your vehicles active exhaust system from your phone via a Milltek Bluetooth app downloadable from the Apple or Android app stores.

This means you can override your OEM valved Focus RS system or for example your Milltek Focus RS catback system with a simple touch screen interface.

Also a great option for a mk8 Fiesta ST!
