Is there a "ram-air" type system available for the 2003 2500HD? Something ducted to the airbox, similar to the FTRA. The Volant scoop won't fit the HD, due to the larger frame rails. I've seen the K&N, Air Raid, & UPD systems, but they all draw air from the fender duct, or underhood.

Thanks,

Mark

 

Use a UPD and make your own ram air. All you have to di is use some dryer ducting. Rn it from your tow hook up to under the air box. Cut a hole in the bottom of the air box and stick the airduct into air box. Viola, cold, ram air!!

 

I've thought about something along those lines. Anyone out there got pictures, or a stock airbox that would like to sell?

 

There are pics around here somewhere. 02Denali I think done this mod. Let me see if I can round up his pics.
