Need recommendations on Air Filter

I upgraded to a Greene Air Filter, but had problems with it because air was leaking around it. I got my money back and am trying to figure out what to put in next. I am not an off-roader or into excessively powering it up. I have the vehicle because I have a huge family. My default it to go back to the Ford stock filter unless convinced otherwise. Input or points to old threads (which I could not find) would be appreciated.

Cheers all
