Re: AiRaid filter vs Spectre
In general, oiled gauze filters often flow best. However, they also let more gunk in, and they are a pain to maintain. One instant reading of your EVIC is not a very reliable test. Average your MPG for a month with the Spectre, and a month with the Airaid -- driving the same routes, same style, similar climate, same gas, etc. There are too many factors in MPG -- to say that the filter did anything. If your old filter was quite dirty, any filter would have improved your MPG.
