I replaced my front opening Cobra II scoop with a small 2" high rear opening cowl scoop and lowered the engine compartment heat by 30 degrees as tested for a week in 70 degree temps. I like the outcome but not the looks. I saw this bolt on scoop with hidden flange on this site and like it's looks much better, does anyone know who makes it?. I really don't want to glass and bondo a cowl on because my paint is perfect. I presently have a 14" hole cut in the hood under the scoop to vent hot air out. With 115 degree days right around the corner I really want to run cooler this summer.
