FYI the factory air box is as good on a stock motor as anything made and won't give you water ingestion problems . it may not look KOOL but it works. when and if you put a supercharger,or other serious mods (heads and cam,headers or bored and stroked motor ) than by all means go for it but with a stock motor you will not need it and won't see any increse in power at the RPM's you will run your H2 at .
if you must spend the money than Volant at least has a good box that keeps most of the engine copartment heat out and sucks in mostly cool air . and you will get that Kool sound with the factory silencer removed .
