NGK TR55 plugs seem to be the part of choice. Autozone doesn't carry them. Where are you guys getting your plugs? NAPA? other? My 92 SSEi is already misfiring, so I don't have time to wait on delivery.

I bought mine from Advance Auto, but many people get them from Napa. I picked up some NGK TR 55 V-Power Copper plugs... very happy with them.

The guy at Advance pretty much looked at me like I was an idiot when I said that I wanted COPPER for my supercharged engine. I told him about everything I have learned on here, and he said that somebody is feeding me a line of B/*. needless to say, I will be going to Napa from now on for those plugs.

Ask for NGK 3951s wherever you go. That'* what they go by.

I can get them locally at several places, but Autozone isn't one of them.

NAPA, Advance, O'Reilly all stock them. As advised above ask for NGK 3951.
