Default 96 spark plugs

I have been wrenching a long time, but I looked at afriends 96 today, and I am at wits end on how you guys change these plugs.
You guys have a thread/link/video/tutorial/insight as to how?
It's tighter than h*ll in there.
Thank you in advance.

Extensions and a swivel spark plug socket...and removing part of the fiberglass inner skirt. It is bad but at as bad as you might think.

Like I showed the guy who dynos some of the Corvettes I work on. IF you can see the spark plug...then that can be your path of your extension so you can get to it.

Getting some parts off so you can get in there and disconnect the spark plug wire boot. And that is when I generally cuss and want to smack the last person who messed with them and DID NOT apply a small dab of dielectric silicone to the snide of the boot so it less likely to stick to the porcelain of the spark plug.

The worst plug for me seems to be #6 cylinder.

I found unbolting the ASR and setting aside opens up 1-3-5-7 nicely. #8
on the other hand is my nemesis.

I think it was three 10mm nuts/bolts and it can be moved to the side?

And when the center fiberglass portion of the lower wheel house area comes out also ( the aprt that goes over the shock and upper A-arm area.....if my memory serves me correctly.

I do know that when installing the spark plug wires it is a MUST!!!!!!!!!

Just try not to man-handle the ASR unit to much. IF the cables are really cold...they can snap if you are too aggressive with it while moving it.

ALSO...do not be surprised if you need to detach the fuel lines from the clip that is holding them on the A/C evaporator case to move them slightly so you can get in for #8 cylinder. I leave the fuel lines still connected....I just move the lines slightly so I can get my extension down in to the plug.
