I bought the Airraid one a few years ago now. Did it make a difference. a little, Would I do it again, I am not sure. I noticed much more of a difference with the electric fan and header additions. Every little bit helps on these rigs. I know a lot of the Charger/LX guys hate them and say they are worthless. I do not have one on my charger, but that is also a totaly different machine.
