I used both hands and had both eyes open, so it only took about 20 minutes. It's not hard at all. If something is in the way, move it - don't try to fight around it - that's what takes the extra time.

My question is does it make any difference when you start up the engine or when you push it hard??

Pretty simple. Took about 15 min. to do all of them, when I switched to 1step colder iridiums during my S/C install. Even with everything else installed, I pulled them to check later and it only took about 20min.

I read somewhere that if you use any type of plug besides stock, it will cause the car to idle rough. Any thoughts or comments on that?
