Actually they ar enot bad just move some section of harness out of the way on the back ones, just remove a couple of bolts holding the harness bracket.

If I had to do it again I dont think I could do it in 30 min, 45 tops, but def not 30...this isnt a Corrado ![](https://my350z.com/forum/images/smilies/icon39.gif)

corrado's are a PITA to do the plugs. you gotta use a special spark plug wire removal tool to get the plug wires off, and that can be a pain, especially if the wires are stuck, because if you break the tool, you have to remove the intake manifold to get the wires off. (add 40 mins)
then you have to get the spark plug socket down in there and on the plug blind.
it takes around 45 mins to do if everything goes right.
