Not that I know of. I personally would not make one either because Carbon Fiber happens to be a very good conductor of Electricity. I've heard of issues with overseas companies making carbon fiber spark plug covers and had problems from the electrical charges affects all the wires. What happened was that in an inline 4 engine, when the #1 sparkplug fire, it would leak some current into #2,#3,#4. This caused the engine to misfire and wobble. This is very bad. So if you have a carbon fiber cover over the alternator, it might conduct the electricity and cause a short to the body ground.
