I was excited to order my filter and replace it with my old one. In doing so I found that the filter for my BMW 5 Series was not an exact fit even with ordering the correct filter. Overall I'm disappointed that it was a waste of my order and have no choice but to return it. I'm not sure if I would order this particular product again.

Over all I am satisfied with my K & N filter. I have replaced my stock filter with the K & N on every performance vehicle I have ever owned. Not sure if it has done a whole lot in the performance department, since I am not conducting any 1/4 mile speed runs, but when I get into the throttle I can now here my turbo spooling up. If I am getting more air flow I can't see it being nothing but an improvement with the turbo.

After getting on for a 3 series I also own I was surprised by just how easy the one for my 5 was to install. I wasn't under the hood 5 minutes to complete the job. While I haven't had this filter in but for a few days, I'm expecting similar results to all of the others I've installed in my cars. Typically 5-10% better fuel economy so it doesn't take all that long to recover the initial cost.
