iridium Plugs
Went to the local autozone to get some goodies for a tune up. Told the guy i wanted AC delco origianl plugs. (platnium) and he said all he had in AC Delco was the Iridium ones. They've replaced the platnium with these. He showed me the screen, and he was correct.
SOOOOOO, a few questions.
1. Has anyone used these yet?
2. Is what he said true?
3. Do they need to be gapped to the .060? (3.8 engine) Did some reading on web, and some say they come pregapped from factory, others say they gap them to the specs.
I sure hope they perform well, for a little over $6.00 a plug.
Thanks
Paul
