The air filter improved my performance, but no improvement in gas mileage.

Second one I have owned. I prefer the dry over the oil filter as a precaution to preserving the mass air flow sensor. I would buy another one.

02 745i Filter

I would like to know how many filters come in a box since my 7 takes a passenger and a driver side cabin air filter.

These are air intake filters for your engine's intake system, not cabin air filters. Unfortunately, we do not carry cabin air filters, those would probably be best purchased from your BMW dealership.

aFe ProGuard 7 Filter

Will using this filter void the factory warranty on my 2011 F-250 (Power Stroke)? Thanks.

No it will not. Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts. Check it out here: Magnuson Moss Warranty Act.
