Review on 🚀 High Performance K&N Cold Air Intake Kit for 2014-2015 Audi (A4, A5, A6) 2.0L L4 - Guaranteed Horsepower Boost | Model: 69-9508T by Will Rahman

If you're looking for pure turbo noise, this will do. You can hear the turbo coil and the "bubbles". The instructions were ok and sufficient for installation. I would have expected more from a K&N setup. Some parts didn't fit together properly. Not all the necessary screws for installation were included. One screw that was not included was the M5, which is a rather uncommon screw for the average consumer. My mileage has decreased by about 3 mpg. But I am not sure if this is due to consumption. Around the same time I removed some of the plastic under the car because it broke and I haven't had a chance to replace it yet. My guess is that the plastic is responsible for at least some of the mileage reduction. When you get such a power, it's imperceptible. I only did that for the turbo noise. All in all I would buy it again but I expected more from K&N.
