I realise the benefit of good air filtration, and would like to get the same quality of dirt removal that the paper brings, but without the ongoing expense of changing paper filters so regularly....
I guess there is not much in the way of re-useable filters that offer good filtration?
Otherwise I might be forced to go to a good quality pod, and try and fit it in as unobtrusively as possible. I'm moving to a different turbo set-up soon (and that will definately require more air) so perhaps it was ambitious to think I could do something with the stock air box....
