We get asked this a lot, and our experience is anyway you can get more air in to an engine, has to be good.
The thing to consider is cost, whilst the inital outlay is on average between £40 to £60 depending on application, and OEM filter can be 50% less, the performance ones are typically guranteed for 1million miles. so Every service they just have to be cleaned out rather than replaced.
Recent ones include applications on Audi 2.0tdi, Audi Q7 3.0 tdi, Audi A6 3.0 Tdi, Range Rover Sport 2.7TDV6.
All so far have improved mpg by on average 3mpg.
