AC Delco Does not have Iridium

[geoffinbc]

So there is no Iridum plug from Delco for an iron head motor, as far as I can tell.

So my choices are NGK or Denso. I really hate to leave the Delco brand but I am itching to try the Iridium plugs. So which of the above two would you go with.

RE: AC Delco Does not have Iridium

the only real difference I saw was that the Denso has a .05" smaller tip I believe, but was almost twice the price of the NGK.

I get either plug at cost. I am more concerned with build quality and longevity.

I am running these on a Crane Fireball ignition with a 510 mA peak gap current

Well I went with the NGK plugs. I paid 8.50 each. I had to regapp them to .060 and then installed them. Everything so far seems great.

I really didn't like the idea of not using Delco. But my buddy at LORDCO said if they dont perform like you want them to then bring em all back. So I couldn't pass it up.

I will post back in the future and report of the langevity under my abusive driving style

I found the NGK's for 6.99 each... um.. lower price.

CDN vs. US dollars.

See, some times you have to find your own way.
Good find.
Do you have a part number for them?
