RE: Do motor saver air filters boost hp + performance?
I don't know... There is a lot more surface area on a 360 degree motorsaver style filter compared to the old conventional through style, like some(traxxas) trucks come with. That should allow it to draw air easier, although the difference would be really small I'd think. Any benefits would compound with rpm. I do believe they will allow close to optimal performance for a longer duration between cleanings, again because of the larger surface area. Probably not much of a difference, but it has to help.
