It works when the car's in motion by sucking air out of the cabin thru grilles in the rear edge of the doors. Hall's been selling that system for years and it apparently does work. Not too hard to install, either compared to installing one that works with ram-air at the cowl. As to how effective it is, I've not driven a Pantera with it on. <BR>

I added two home-built cowl intakes to our '72 and they work pretty good for being only 1-3/8" OD. But one really should pull the dash to install a system like mine, or like the stock '74 system which is even more complicated/expensive.
