Yeah, I was looking at this on the Bean Garage thing tethered to this site. The description doesn't mention fuel economy, but it increases acceleration and ultimatly increases the "health" of your engine in the long run (or more rather allows it to have less wear&tear from using a regular filter). I was wondering do any of you all know or can explain it's impact on feul efficiency? Or is it more of a "well, depends on how you drive" type idea.
