Took the air box out of a SVT Lightning truck, cut a hole for the fender ducted air and another for the cowl inducted air (after extensive fitting. Had to relocate the large wire connector and move the AC pressure hose over 1 1/2 inches to the passenger side to make room for the cowl intake hose. I then reshaped the strut tower a little for some more hose room. Then I cut an opening in the firewall to allow the hi-pressure air in from the cowl area of the windshield. Then I modified the plastic cowling to allow the air to blast down into the cowl from the windshield to the intake pick-up in the firewall. The intake pick-up has a flaired and screened end inside the cowl area that is shared by the wiper mechanism. It is elaborate but makes a big difference from 2500 rpm up. The fun thing is running it hard and then jumping out to feel how warm (COLD)the MAF is. It is always COLD! Not warm, COLD. I enclosed the MAF to keep it cold as well, not just the filter like most boxes. The SVT air box is thick construction with great heat holdout. And the best thing.... it's SVT all the way. This is my third air box and I am building my forth which will incorporate the full intake system and the cold air box as one complete system (1-piece). I am also adding a solinoid accuated flap to close off the cowl inducted air for cold weather operation when needed and a temp guage for the MAF.
