Chris Pluch, Toronto, Canada
I saw an immediate improvement to both the performance and fuel economy. Neither were startling but both were noticeable.
Athul, Kitchener, Canada
Fit fine, but a little more loose than stock filter on my 2013 A4 quattro. I would recommend this.
Vance H. Nooitrust, Amsterdam, The Netherlands
This is by far the best airfilter for an Audi A4. Had it since the first delivery of the car and it is a fantastic filter. Not only filters but it makes the engine run smoother and the mileage per liter improves dramatically. An excelent filter.
