Did you read the rest of this thread? The best recomendation for a CAI is to stick with the CAI that VW put in your car at the factory. All of the aftermarket ones either filter worse or cause other problems. Your car came with an excellent CAI and unless you have done some serious mods to your car (like bigger turbo), it will pass far more then enough air for your engine.Anyone have recommendations for a cold air intake for the 2.0L TDI, I have been looking around and found that aFE sells a intake for the 2009 tdi jetta but I am not familiar with them and am not sure if its worth the money.
A CAI can have a noticeable effect on a normally aspirated gasoline engine, but your turbo charger is more than capable of giving your car all the air it needs. Save your money and put it where it will actually do some good.
