iv got a ek9 and want to no if it will make any differance to the breathing if I put a after Market induction kit on it or if I should just keep the stock airbox?
If its too make any difference at all it would need a direct feed of air from outside the bay! Even then the difference it will make you probably won't even notice! And like anything you get what you pay for with induction kits! You could spend your money on a better mod really!
