What do you mean by efficiency ?
If it's pressure drop, like in their adds, unless your commute involves more than half the time at full throttle, the lack of restriction will be compensated for by a (slightly, very slightly) more closed throttle, and no change in "efficiency".
If it's filtering efficiency, as you know, there are way better.
