Review on 🔧 K&N Engine Air Filter: High Performance Premium Washable Replacement - Fits 2010-2018 AUDI (A6, Quattro, A7, S6, S7, RS6) by Adam Gambel

Easy to install on Audi A7 2017. You will also need a screwdriver to loosen the metal rings. Installed in summer. No problem. There is definitely a noticeable acceleration, which makes me very happy. Can't tell if fuel economy has improved as I haven't driven much during the pandemic. The great thing about this filter is that it can be reused, saving you a lot of money compared to buying a real air filter. This may look expensive now, but it will pay off in the long run. I have had a lot of experience with K&N products over the years.
