1. A/C, Power steering, and water pump
2. The serpentine belt is still running them, just not as fast.
3. Yes, but mine doesn't seem to blow as cold when idling
4. I paid $75 to have them installed, my compressor wasn't powerful enough to run an impact gun to get the crank bolt off. Took about 45 mins to install.
5. Steeda
6. Yes, it's cheap, and you have to take it off anyway to get the UDP installed.

To be honest, I didn't notice much of a difference after having them installed. That being said, I do believe that it free's up some power, I just didn't notice it.
