Basically if you want to have a front mount and not get pinned evertime with a defect you need the stock airbox, there is nuthing wrong with it people are running 300kw with them, well with regards to the induction noise if you have a aftermarket turbo and a metal intake pipe you will still hear a little bit not much but with the stock turbo wont realy hear anything with the stock air box. So as I have gone from a pod to a airbox as I got sick of the defects evertyime and especially now theyll prob epa you aswel for having it.
