i was thinking about derestricting my airbox this week end but i only have the standard panel filter at the moment, would it be worth doing or should i leave induction kit in?
I have got the standard filter on, and still derestricted the airbox, you will notice some differance in your driving with it been done.
derestric the standard panel filter easily done, although can be a git to get the pipes out . Worth it as its a free mod .
I found once i de restricted my air box and fitted the veccy c pipe i didn't notice much difference but i noticed a bit, then i fitted a k&n panel filter the next day and i noted a lot of difference! well worth if it you add a new panel filter as well but if not you will still notice a bit but not much.
after market filters make you use more go-juice anyway
