Also, just looking at the drivers side, would it not help to remove the AIR tubing first - looks like only a couple bolts to move it out of the way for better access - is that right?
Yes, a 5/8 spark plug socket, a swivel and about 8 inches of extension will get the job done. I just used a few zip ties to pull/hold back the one vac tube and that was enough room to get that pesky #7. No need to unbolt any parts. Just be patient and take your time. It's really not *THAT* difficult.
