I have a used black JLT CAI that has only been installed in my '03 Cobra since July. The filter and all the parts are in great condition. The black tube has scratches on it from rubbing the hole through the fender.(typical) I don't think there is any visible damage while it's on the car anyway... im pretty sure the scratches are on the underside of the pipe. Either way, I am only looking to get what I paid for the replacement model of it which is $110 shipped.
