who uses them?

hey ali_n1.. the tC comes with iridium tipped spark plugs from the factory..

i have iridiums..

Anyone know where I can buy some? I need to replace my spark plugs..

Thanks,

hey takumijr..
have you tried the scion/toyota dealer? the sticker under the hood says NGK or Denso.. probably also be able to find that at a local auto parts store (or they could get them for ya)..

Yes I know I could get from the factory. I'm looking to see if there's like a better ones from denso, like higher heat range etc...

yeah i hear you.. best bet would be to ask denso.. maybe a google search for their website?

i use denso iridum plugs in my cars...there is none better

yep. densos rocks. ngk is good for plug wires but not plugs. you can find iridium densos on ebay for pretty cheap. ( cheaper than just about any store)

I don't believe any Scion uses Iridium tipped plugs from the factory... most are Denso, some for an odd reason are NGK but none are Iridium.

Many Toyotas come with irridium plugs. Toyota sources plugs from ND and NGK. Irridium plugs DO NOT increase performance, but they have a longer service life.

The TC does come from the factory with Iridium tipped plugs.

It is part of the no major service until 100,000 miles.

i 2nd that.. just read the owner's manual.. it does come from the factory with iridium plugs..

Hmmm that's odd. The xA/xB/Vitz/Echo don't get Iridiums from the factory. But, it makes sense that they would use them, I mean... Denso is Toyota's company... why wouldn't they use their best technology?

It costs more.
