Hey everybody I have a 2009 fg xr6 turbo ute, that I have just started giving it some performance mods. So far it has 1000c injectors and a tune making about 275rwkw. I have been looking at upgrading the stock air box, but can't make a decision what I should do for example a plazmaman intake air muffler delete pipe intercooler or like a cold air intake. Any comments on them or advice on any other ideas?? Thanks for your help
