My idea is to make it recall the 70-71 cars, a blue lid would not look anything like what you'd see in a 70-71 Challenger, so the orange to make it look similar to the original oval air cleaner lids. With the cover off it just looks too busy with all the wiring and fuel rails IMO. I like the way the SRT's have the heads and fuel rails covered but the intake uncovered. It's an easy change if i decide on a different cover color, 2 hrs and a can of paint!
