Very easy to install and replace the stock air filter. Small improvement in performance and economy. I think my suv was restricted on air flow.

I replaced the stock OEM filter in my 2008 BMW X5 with this one. There is a slight performance increase, or at least perceived. But I don't know if that's a 'placebo' effect or the real thing. So, I'm going to get another one for my girlfriend's 528 and not tell her I'm installing it and then ask her after a few drives if she feels a difference.

The filter has transformed the performance of my car. Where there was a seeming struggle to breath there is now plenty of air. Shifting has become much easier for the car. Acceleration is vastly improved. Fuel economy has improved. Your product rocks. I will be using your filters from now on. Thanks!!
