I just recently picked up a 2005 Roadster with the standard 5.0 engine. It runs great and has plenty of power. When test driving I wasn't in the car long enough to notice this problem. But on the way home there was plenty of time. There is a lot of air flow from the engine compartment around the sides of the footwells and into the cockpit. The air starts cold but as the engine heats it gets very hot. Like you have your regular car heater on full blast. How do I stop this air flow? I could probably fashion something but am looking for the right solution.
