I too am thinking of how to do a ram-air system. I have a 2001 V6 and really like the Shaker hood scoop at
http://www.classicdesignconcepts.com...splay/460.html but the price is way out of my league. As I understand it, the ram-air will only help increase H.P. around 50+ mph. However, any time you can get a free boost its worth it. My other thought is to funnel the air from the entire opening between the fog lights into a single 3” tube running up to the CAI system. This would require some sheet medal fabrication to make the funnel. The opening is about 24”x2.5” (60 sq”) and the 3” CAI system is 9.41sq” (about 6 times smaller) so… I feel cramming all that air down the throat of a mustang should do something!
