I'm the one that put these in, too. I don't remember whether or not I used anti-seize either. I know I used it when I replaced the O2 sensors. Would there be residue on the plugs if I did use it?
Man, if I didn't...what an expensive mistake! I've learned alot here and have saved some money doing some DIY repairs/upgrades. Hopefully someone will take notice here and not repeat my (possible) mistake.
