Lately I've been running my dual fours without the filter element inside. Just goofing around and trying to see if I feel, sense or can measure any difference, like in mpg or something. Haven't quite decided if it's good or bad, as far as power/performance goes, feels about the same. We don't have a track anymore so I have no way to measure it at the 1/4 mile. Yeah, I worry a little about dust/dirt getting in there, but heck it's not like were driving on dirt roads.
