Are the Motorcraft plugs pre-gapped?

[Fourth Horseman]

I forgot to ask when I placed my order today (Thur. the 8th). I read that the Denso plugs are shipped to customers pre-gapped. Am I correct in assuming the Motorcraft plugs will be similarly pre-gapped?

Thanks!

I doubt it. Denso's are pre-gapped because the Iridium metal that makes them up is very brittle and won't bend.

If the Motocraft's are copper, the will 'gap' themselves in the package, so check them :)

Copy that. Thanks for the help. :up:

^^^what Dr Caleb said^^^

Actually, iridium is only used on the centre electrode. Although the ground electrode is adjustable and the plugs "can" be re-gapped, due to the brittleness and extremely small diameter of the iridium centre electrode (0.4mm), using a conventional round-wire feeler gauge or the circular "coin" type, can damage or break the tip.
