I saw this on a new Plum colored cruiser and thoought I'd give it a try. It showed up a lot better on a dark colored car. I took off ALL the rubber surrounding the engine bay and covered it with a chrome strip. I think it looks good but I know all the die-hard techies out there will tell me something bad about the air flow. I took the PT to a show in St. Pete which is 108 miles one-way and the temprature never went above half way (like always).
