take the induction kit of mate and put it back to standard as more or likely you will be loosing power from this to begin with, and put a panel filter in it, itg or pipercross, then after that cat back exhaust, matched inlets, silicon induction pipes and remap. some people on here do change the airbox to a clio v6 airbox or the R3 airbox, the R£ is very expensive and the clio v6 box is alot of farting about. you will be better putting the standard box on cus no other induction kit actually gains the 197 any power
