Wonder how the difference would be noticed if at all on a boosted motor...

I stuck with the OEM plugs since I figure the Toyota engineers used Iridium for a good reason besides service intervals...

Point is , the iridium is not a miracle plug , needs to be replaced sooner than 100,000 miles . Replace at what mileage you feel comfortable with by doing it yourself or a trusty mechanic . Have used N.G.K. in past TOYOTAs with good results . Like posted before , had the DENSO iridium in a 2000 COROLLA changed with NGK iridium ( bought at A.A.P. ) by a service center at around 75,000 miles ( give or take ) and the car ran better . Little more pep and small gain in gas mileage . Even the other 1/2 noticed it .

Toyota owns most of Denso and that's the reason why they use Denso plugs and other denso parts.
FWIW, My '02 Celica came stock with NGK plugs and they were perfectly fine. I assume that Toyta used the NGK plugs whenerver there was a supply plroblem with the Denso plugs. Personally, I do not know if they still use them. |

Dude they have not been a part of toyota for 62 years >> http://www.globaldenso.com/en/aboutd...ory/index.html Denso and NGK both bid on contracts to supply all automakers with their product from the factory. Denso happened to win the yaris contract. Nothing to do with ownership but rather dollars and cents. Denso and NGk also private label their products for toyota and numerous other auto companies. That is why if you buy from the dealer some will have denso on the plug but a different part # which is usually the toyota part #. Denso will also assign a different part # to signify that it is a toyota private label plug.

However, as I understand it, Toyota owns a large portion of Denso stock so, yes, Toyota owns part of Denso. |

just an update on denso iridium gap from my research.
bigger gap vs stock which is normal and the iridium part of it will compensate for bigger gap..no need to adjust but you can.. |

On the echo i always left it to 10,000kms and used synthetics, no issues. In 258,000kms on the echo I changed plugs twice, always worked lovely, and I used iridiums. New Yaris with only 32k on it, likely has OEM plugs in it, I may change them up soon just for the hell of it. |

what the hell happened to this thread? lol, it started out so nice......
very nice plugs at 120k, those can almost be put back in and used for a while longer. on my moms camry which is at just shy of 300,000km its only on its second set of plugs, firs set wernt changed untill almost 190,000km. the random plugs i put in still look very good. my way of thinking are, plugs are plugs, trolls are trolls :)
