A decent air filter is possibly the most basic of tuning mods and an absolute no brainer when it comes to getting your engine breathing properly. These brand-spanking-new PRORAM jobs though, are clearly more decent than most.
Always the way, eh? You wait ages for one awesome Ford product and then two of the buggers come along at once! This time around though it’s all about getting your Mk3 Focus RS breathing properly because, obviously, the latest 345bhp, Blue Oval-badged bruiser isn’t quite rapid enough!
