one, it will work, but you will run into the problem of where to put it: you can put it in the middle of the pipe, no room. you can't put it at the top - MAF is there. and putting it at the bottom of the pipe is a waste of money cause it is at the same hight as the filter. if you just put a splash gaurd on it, then you would have to submerge the entire front end of the car to hurt it really. and if you did this with the ABV on the lower section of the pipe it wouldn't make any difference. also, look in the install section, there is a custom fabricated splash gaurd in there that works just as well if not better than the idea behind the Injen
one, and much much cheaper.
