Question:

I want to get the original AC Delco 41-921 plugs that have lasted me 97,000 miles, but where can I find them?
The accepted replacement are the Irridium 41101, but why should I change to a plug that may not last as long. Please let me know if I can get these for around $7 each. I have a 2001 Buick Regal - Supercharged 3.8L. I'm looking for the OEM plugs and not just the newfangled replacement that is more profitable to sell. Please don't post any answers like "the autoparts store" or "do an ebay or Google search".
