Well i seen Ken talk about them, seen them on Ebay..and thought to myself..i could make one of those! So i took a tube of solid alum, and used the ladith...(i can work one..just cant spell it!) and made one out! Ran it for a few minutes to check for leaks, seems ok! I doubt i'll see too much temp difference, i only put it on the top rad hose..maybe i'll make another for the bottom. ANyways..the pictures in my profile..oh and i got some new ones of my air scoops..felt the flames where a bit too dangerous..so i cut em off..let me know what you thinK!
