Loved the look of this filter which opens up the end of the Ford Focus ST air box which with standard OEM filters is blocked off by the end of the filter. Others claim this improves the induction turbo sound considerably, in my case it makes zero difference to sound or performance. Maybe it’s the placebo effect for them I’m not sure, can only speak as I’ve found Delivery was next day & Mountune boxed it up very well indeed, they have a very efficient professional delivery service.
Super quick delivery, easy fit and sounds great
Excellent service throughout
