These filters have been tested to work well with the MAF elements used on many audi vehicles. We found after tuning MAF based Audi and VW vehicles over the years that certain styles of air filters can cause your MAF sensor to read incorrectly; which can lead to quite a headache when you go to tune the vehicle or are trying to sort why the car may be running rich.. To take the headache out, we have found and tested a quality K&N 4" air filter that works without issue at a reasonable price.
