The hesitation from my slow throttle response just disappeared and from hitting the gas it is pure power.

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.

The first one I used only lasted 30,000 miles before it was noticeably dirty throughout the inside of the flutes, but that's probably because of the polluted city environment my car was driven in. The Volant air filter did a great job in keeping the throttle body clean, better than the K&N reusable filter it replaced in the cold air intake system. When the Volant is new, it may provide a slight throttle-response and gas mileage advantage over other types of filters common to cold air intake systems, but when it starts to clog there'll be a noticeable drop in gas mileage and throttle response. When I replaced my dirty Volant with a clean one, the improvement in throttle response was instantaneous. This is an excellent air filter to use if you don't mind spending the money to replace it every 30,000 to 40,000 miles.
