K&N 33-3079 Air Filter Product Reviews

Monday, September 24, 2018 - Part 33-3079
As efficient as always in delivering the above filter. The good quality filter makes a noticeable difference in the performance of my car at any rpm, & is well worth the money it costs.I used them before for other BM's & have never been disappointed.

I know that this is the best air filter made. But on a 2018 BMW X-3, 30i Wrenches you need you take the car to BMW.
