Question about 2004 Cadillac CTS
I actually just finished this task this morning. If you have the 3.6 liter V6, you'll need to remove the intake manifold bolts to get to all of the spark plugs. You don't have to disconnect all of the hoses going into/out of the intake, just remove the bolts and disconnect the small airbox in the front of the car. There are 6 bolts in total. Get something you can use to prop up the entire intake assembly about 1.5 to 2 inches (you only need to do this on one side at a time). Be wary if you have a paper gasket under the intake though, that will need to be replaced. Buy it ahead of time just in case. I unfortunately learned that one the hard way :(
