It will help if it changes the MAF signal in the right direction. Aside from turbulence factors, air filters sometimes cause the engine to lean out slightly, as the ECU is receiving more air than it thinks it's receiving.

Air filters can and sometimes DO change economy. The problem is they usually do so for reasons that have nothing to do with the filter media and everything to do with the shape of the filter and the filter installation.
