my question is how the hell do you get to the plugs on the f-bodys? especially the back ones? anything special or is it just time consuming? any pointers would be greatly appreciated.

Basically take out as much **** as you can to help you get to them. Then pray.

It's pretty easy to do the plugs with the coil packs out of the way. Don't try and fight them, you'll waste alot of time. I just take the coils off and hug the block with a shorty ratchet for #8.

 

Longtubes and having the AIR system removed makes changing plugs a hell of a lot easier. I get #1-7 from the top and go under the car for #8. Never removed the coil packs.

 

Agreed. I had mine out and back in again in about 40 minutes.

 

The passenger side is the hardest, with the #8 bastard being the worst. Do yourself a favor and spend $14.99 at Home depot, Husky Pro Indexable Ratchet. I am certainly no great mechanic, this tool will have all 4 plugs on the passengers side out and back in about 15-20 minutes with NO struggle at all. The drivers side is a cake walk, another 15 minutes and you're done.

Here's what the tool looks like (check link), the Husky tool is a little different but does the exact same job. #8 plug...Pull the plug wires off, reach back with your left hand and attach the spark plug socket, then again with your left hand connect the ratchet to the socket, than with your right hand break it free and ratchet it out. Its almost effortless. The rest of the plugs are pretty much easy going. Hopefully the last person to put the plugs in didn't crank the **** out of them, thats the only thing that makes #8 hard to get out.
