how hard is this kit to install is this a bolt on kit or is modifications required and if so how many and what?

how many people here are running this kit and could you tell a noticable difference?

what all comes with this kit and is it worth the $330?

 

HELLO IS ANYBODY HOME?

 

Gonna have to wait more then 1.5 hours. Alot of people run the MSD and they usually only check this once or twice a day. From what I hear its easy and worth the money.
