RS500 Airbox [Mk2 Focus RS]
£82.50 GBP
The only Ford-endorsed Mk2 Focus RS airbox upgrade - as used in the Focus RS500 and MP350 upgrade...
mountune’s involvement with the mk2 Focus RS began more than a year before the vehicle’s public debut back in 2009. From the outset it was clear that to increase the power output significantly, an improvement to the airflow capacity on the RS’ OE intake setup would be required.
