Lower Air Box Mods

[BigDave]

Does anybody if there are any companies that make custom lower airboxs? Also could I put mods on the stock lower airbox without drilling a bunch of holes in it? I have a smoked UPD (NSV) intake and I am wondering if the lower airbox could be restricting the intake from its full potential?

Dave,

I have a nice instruction sheet with photo's posted on my site for a great air box mod. Since then, I've run a 4" tube down to the front tow hook hole and mounted a scoop. Works great!
