Easy on my car, no emissions, no ac and I have headers. Takes maybe a half hour including a beer break. Like everyone else said the passenger side coil bracket must come out. I only use the front three bolts to hold each coil bracket in. I used TR55s gapped at .055. If you think the back plug on the passenger side is a bitch try threading an air hose in that back one to keep the valves up during a cam/valve spring install.

 

If you use NGK plugs you should read their website as why they say not to put anti-seize on their spark plug threads.

NGk TR55. They are cheap, readily available, and work.

 

This thread popped up saying I had already posted in it. Not recalling doing so I clicked it. Then I realized it was a thread from 2010. Explains why I didn't remember posting in it.

 

I am thinking the right front wheel could be removed and you could make a hole in the inner fender with a hole saw to get #8. Afterwards you could cover the hole to keep water from splashing in there. If the car is never in the rain you could just leave it open.

 

02 camaro z28 here. all stock with all the emission crap still on it. After checking with this site I removed the air lines to the exhaust manifolds. The coil rail and plastic cowl on the passenger side and got the #8 plug from the top. Just used standard 3/8 ratchet and plug socket to break it lose and then added a universal and pretty much spun it out by hand. Thanks again for the advice.

 

Last night I attempted finishing up an exhaust job I did by swapping over to new long tubes and yada yada. I ended up doing plug #8 with the coil bracket still on and I wont do it again. I was just being lazy and didnt want to pull the coils just for that one plug. I will not do that again, my arm is beat up bad lol.

 

Changed my plugs and added MSD wires today. My first time.... Did all 8 from up top. Did remove the AIR tube on passenger side, along with the coil bracket. And didn't bother with reinstalling the rear bracket nut. F that thing. I didn't think it was as big of a nightmare as I've read all over the internet.... Didnt need a swivel socket, universal joint, or anything special. Just sockets, ratchet, and a wrench. And I don't have tiny hands... Either im that lucky or that skilled.

 

I also yanked the passenger side coil bracket to get to the back plugs. The biggest problem was trying to get the rear passenger plug wire fully plugged in again. I had to spend quite a while fighting with it. Still easier than the rear plugs on most transverse v6 motors

 

I know this thread is old but bammax how did you get the rear passenger plug wire fully plugged in again?

 

I wedged my arm in there and managed to get the wire on the plug by pressing and twisting, then I put the coil pack in place and attached the wire to the coil before I bolted the coil pack down. It was mainly just wiggling things and focusing on that one plug wire before I did anything else. Having the coil loose gives you a bit more slack to get everything plugged in.
