Every car I have runs with K&N filters for a reason. I'm very happy with the performance I receive.

Although I don't have enough data to make a truly informed decision, this air filter seems to work great for my 2013 BMW 5-series. I like the fact that I can clean it regularly, and it seems to be a high quality build. There are some articles testing this filter online, and it seems to work better then OEM in some respects, but with some tradeoffs that are OK for my needs. I enjoy owning this filter for my needs.
