Sheesh.
I was prepared to be patient with the #6 plug...
I was not prepared for the fact that the plug wire boots are a b*tch to remove and a b*tch to install.
I won the battle of the nuber 6 plug with a wiggly extension and several other short extensions. It is possible (on my 2003 non s/c) to get your hand in there and feel the plug and boot. I did sustain some battle damage but, in the end, I vanquished the evil plug.
cheers,
Nick
