E350 Cold air intake modification

Has anyone made any cold air intake modifications on there E350 class C? I have a 1992 E350 chassis class C with a Ford 460ci. The factory air intake seems so restrictive. I have searched the net but can't find any cold air intake kits for this age E350. It seems like my RV would perform much better if it could breath better. Anyone have any experience with this cold air modification? Any places you could refer me to find a kit? Any pics of you modification?
Class C

    Are you subject to annual emissions testing? Any modifications could cause problems.

    Only had our 1991 in sig (it's an EFI) for a month, and no serious driving time yet, but my idea on that sort of thing is that if it has been like that since 1991 and it is still going----who am I to go changing things like that?

    Do you mean for the radiator or for the air into the engine via the air filter?

    If you have had some sort of issue with power or whatever, there could be lots of other reasons why besides air intake. ???
