I purchased the AEM DryFlow air filter for my Audi A4 2.0 turbo a while back but wanted to fully experience and evaluate the effects of the filter for a few thousand miles before submitting a review. Impressions: 1) Incredibly easy to install. 2) Low end acceleration is noticeably improved, rpms run up faster. 3) I was amazed to gain about 2-3 mpg increase in city driving and up to 5 mpg gain in long freeway trips! I've never had 35+ mpg on a road trip before. Buy AEM now!
