CS,
I'm going to combine your two threads and keep them in the C5 Technical & Performance Forum. No sense having two threads on the same subject, after all.

Sorry, i don't know how it posted twice?

No worries, CS. Hang in there, I think you'll get some responses from folks who've done a spark plug change on a C5 soon.

Changing plugs on a C5 is a piece of cake, compared to a C4! A good set of sockets, including knuckles and extensions; maybe a T-handle. Use anti-seize on the new plugs. Only a couple of things to (easily) move out of the way. Do a search in this forum; there's lots of help here! Good luck!

HI there,
NEVER NEVER NEVER use antiseize on spark plugs, EVER!!!
This creates alot of different problems.
1 drop of synthetic motor oil and torque to 11 ft lbs is all you need to do.

After reading all the spark plugs threads and asking some friends what plugs they used in their vettes, I became real confused on which plugs to install. Asked five different people and got four different answers. So, based on all that, I went to my local chevy dealer and purchased what Chevrolet calls for, a set of Ac/Delco #41-985 iridium plugs and a set of GMPP red plug wires. After about an hour or so, a few skinned knuckles, and three or four beers, I got them installed. Cranking, idling, and acceleration, awesome!

Why is that? I was told to use alittle antiseize on my new plugs when I purchased them. I don't know either way. Thanks for all your help.

HI there,
The reason for NO ANTISEIZE, is that depending on conditions, it can actually LOCK the plugs into the holes, creating a ground source issue and misfires. It also will change the torque required to seat them.
The sparkplugs actually are coated with an antioxidation coating, that doesnt wear off or breakdown.
Most DIYers feel better with a little lubricant, but its really NOT necessary, so thats why the synthetic motor oil.

Interesting. Not exactly an anti-seize, but I've used Noalox in the past... an electrically conductive compound used by electricians when joining dissimilar metals. What do you think of that?
