The Wix filter for my f250 comes with a foam outer wrap. But it seems to be very restrictive. I'm cleaning the wrap every 4-5 weeks! It gets so plugged that my air filter gauge gets sucked into the change filter zone, power goes down and black smoke goes up.
Even when the wrap is clean it sucks the gauge down 1/3 of the way. Any reason to not pull the wrap off? Everytime I open it up to clean it I let dirt in I'm sure
