The problem with internet car knowledge is that if ONE guy does something that others think looks "Real Cool" everyone does it, they do no reserach themselves. Why not wrap your whole interior so you don't need to use the Air Conditioning anymore? Man some of your guys' ideas are so unbelievable. Thats why checker auto and Pep Boys have that section of bolt on garbage for the Rice Tuners. Also why is everyone one of you so affraid of admitting you own a Chrysler and stop putting all the Mercedes Benz stickers on your cars? I will challenge any one or group of you to discuss the design and building of the Crossfire but I will not let you say it is a Mercedes. I have owned Mercedes and not "entry" level ones, now I choose to drive a Chrysler Crossfire and I am not ashamed of it. Rather proud that I can do what I please.

Talk about internet car knowledge! I'm an engineer, so I know a few things about engines and heat dissipation. For one, headers are wrapped to keep the heat generated by the cylinders in, to create higher cylinder temperatures which in turn, inducts more cold air. This technique is often used by race car owners. On the street, this increased cylinder temp. will cause more wear and tear on the engine and therefore reduced longevity and quicker oil viscosit break down. Header wrap simply acts as an insulator. Nothing really more than treated fiberglass. On an induction system, this wrap will help prevent the absorbtion of heat by the aluminum. The incoming air will continue to cool the aluminum from the inside and the header wrap will prevent the heat from the outside. Aluminum does disipate heat quickly, but it also absorbs heat just as quickly. So, if the induction system created heat, you wouldn't really want to use header wrap, you'd want the aluminum to disipate it quickly. That isn't the case however. The heat comes from the air surrounding the engine; therefore, using header wrap would help keep the induction air a bit cooler.
As for those of us with the Mercedes badges, well, I for one know my car is a Chrysler and for that reason, I left all Chrysler badging in place. I also know that my car is a Mercedes mechanically. All of the components including the engine, transmission, hoses, electrical system, switches, computer modules, and etc. have Mercedes/AMG stamps and part numbers. It is a Chrysler by design and name only. So, to make the connection between the two once joined companies, I added simple, unobtrusive badges fitting for an automobile that had its engine hand crafted in an AMG shop located in Germany! Like it or not, our Chryslers are Mercedes vehicles. More accurately, our Chryslers are Daimler/Chrysler vehicles.
