Anyone ever seen or know where I can find the efficiency numbers for Mann or Mahle filters? (thier websites are not too helpful) Normally I use Motorcraft filters on my Fords and Motorcraft is quite up front with their efficieny ratings. Until I can get an EAO for my S60R (if ever), I'm going to use OE Mann or Mahle filters but I'd like to know thier efficiency rathings- purely out of curiosity's sake
Thanks for the help!
