What is the CORRECT part # for the sparkplugs for a stock 1.8L Vibe..Iridium or Platinum ?

[lexicon]

OK,Ive searched matrixowners, genvibe and corolla sites.There does not seem to be a FINAL answerWhat is OEM for the 2005 non GT VibeSome say Iridium, some say Platinum, is the gap 0.044 ?Some say Denso , some say NGKSo, what is the factory recommendation? That is the question

http://www.sparkplugs.com/resu...32959 Looks like Iridium to me.Hey, our engine is radioactive!!

[lexicon]

The http://www.sparkplugs site indicates OEM is platinum also,...or am I reading it incorrectly...and looks like there are several choices of irridium from the same mfr. .....and looks like there are at least 3 different gaps based on the 3 mfrs.I am still confused.Plz clarifyThanks

Apologies for any confusion.Rock Auto http://www.rockauto.com/ shows Iridium .044 gap as the original equipment.Searched other posts and it looks like Denso is the OEM.Good luck.

I pulled the stock plugs out of my car last weekend. They are Denso Iridium plugs. After 70k miles they are holding up very well. I cleaned and reinstalled them.
