Not Special Enough
I think the volant and AEM are of equal performance if the volant is mounted correctly. If you put a scoop in the hood where the volant meets, then you are doing the same thing as the AEM, getting outside air. If you dont have a scoop, then yes the AEM will get better gains. but I dont see any reason the volant w/ scoop isnt a better option. it isnt a puddlesucker, it has less bends to travel thru and the filter isnt directly exposed to the outside elements. especially on the bottom where all the road grime is.
