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.
Athul, Kitchener, Canada
Fit fine, but a little more loose than stock filter on my 2013 A4 quattro. I would recommend this.
Chris Pluch, Toronto, Canada
I saw an immediate improvement to both the performance and fuel economy. Neither were startling but both were noticeable.
