Guys I wasn't speaking of a noticeable difference and have no data saying one flows better than the other. I just figured that oiled foam would flow less air than a gauze filter but not to the point of needing any re-jetting or anything. I also could be wrong about that as I originally stated.Personally for a stock air box I would probably choose the oiled foam but like the K&N for the pod application, again just my personal preference.

I learned all I need to know about life by killing smart people and eating their brains.
