Are the motorcraft plugs that are available at Autozone the OEM ones or are they the double platinum ones? Where online can I get the Motorcraft double platinum plugs?

I'm trying to avoid the dealer costs.

Thanks,
josh

 

still looking...

 

Bougt my Motorcraft double platinums at O'Reilleys auto parts. Autozone also carried them, but only had 1 in stock.
