Very nice mod for my audi.... Looks great and sounds great, also boosts performance, you can feel it as soon as you swap the OEM intake to the AEM intake. There was just one problem the heat shield didnt fit which was disappointing.

It looks and sounds awesome. The whistle I get mixed with my turbo is amazing and turns heads. I cant wait until I get the full power from it after chipping my ride!

Installed this intake a week ago and I'm happy with it! Wasn't to hard to install, only took about 45min. I reset my odometer to see what gas mileage I was getting with my stock air box and then did it after I installed the AEM intake. To my surprise I got about 50 more miles to a tank with the new intake! No power gains, but sound is smooth and the turbo whistles a lot more in higher rpm ranges.

Ordered from AutoAnything on Thursday, intake arrived on Friday. Installed intake on Audi A4, 2.0T. Istallation took approx 1 hour, and instructions were very detailed and easy to follow. I have not noticed any fuel mileage improvements yet, but engine runs smoother at low rpm/heavy loads. Overall, a good experience.

Bought CAI from AutoAnything after shopping around various websites, and they had the best price and free shipping. Got my CAI in 3 days and was easy install. Took about 30 minutes to install and it was well worth it.
