suppose you could go k and n . I still think the apexi would be best, theyre rated highly too. Just keep your standard airbox put a greenpanel filter in there and paint the airbox red.
I had smotthed airbox and green cotton panel filter first and now have a K&N. The jetex filters flow and filter better then the K&N filters, so out of curiosity I need to run one but having spent alot of time on my engine bay I'm in two minds whether I can really spoil the look with a blue filter.
Sad I know.
