This filter was installed in my 2007 Audi A4 Avant Quattro last week. Performance seems to be slightly improved - nothing like the dramatic claims made in the product description - and it is too soon to report any improvements in gas mileage. Bottom - line is that I would purchase again. My past experience with aFe products has always been positive.
