I am asking because a friend put a drop-in K and N in his Mazda 626 and has consistently been getting 5 mpg more than when using a paper filter.





I'll let you know when my Fram AirHog comes in...

Right now I get 26 - 28 miles per gallon; never checked it when I had my K&N filter installed, before I tossed it in the dumpster.
