Some people have had issues with intakes making their cars run crappy. The stock intake does a very good job if you are on stock turbo and concerned about IATs. If your priority is turbo sounds or if you are upgrading your turbo and getting a custom tune an aftermarket intake can have benefits.

I've gone through the steps of putting on an open intake, getting rid of the intake silencers etc, the biggest jump in sound was going to an open intake.

I personally run the bms intake and have used it successfully on the stock turbo and now with my Vargas unit. If you are going to be stuck in traffic often I don't recommend using an open intake as it does suck in a lot of hot air.

Bottom line is beyond sound an intake does very little on these cars but I can relate to the urge to want to tinker.
