    I can get those ngk iridiums for like 6.49 here at work. Plus my 20% discount plus tax, they come out to like 6 bucks each. I might be able to get them cheaper too

    You can't go wrong with either. I would only buy NGK or Denso.

    Use the OEM Nickle plugs for best results. There is NO benafit to running the Iridiums, or whatever. In some cases, they run worse.

    Did I read somewhere that from the factory on V6's they put one type on one side of the engine and another on the other side? But then I read on a plug changing howto to go back with the better type for all six cylinders, which I can not remember whether that was ngk or denso?

    Any ideas?

    TIA

    NGK is on the driver side, and Denso is on the passenger side. No idea why this is, but my friends and I have ideas. Anyway, I recomend useing all Denso when changing the plugs, as they seem to hold their gap better.

    Interesting....I have actually TESTED these different plugs, and found quite a few times, the Iridium or Platinum plugs cause issues. Best performance has been achieved with the OEM Nickle Denso plugs.

    About $3.50 per plug for the 1GR-FE in my Area.

    I thought Toyota advised against using an Iridium plug in the 4.0

    Oh Yeah!!!
    When I went to purchase the plugs from Toyota parts, the Tech pulled up the standard OEM Denso's (Nickle). I ask whats the Diff between them and the Iridium, and only answer I got was life of the plug: ie.. 30,000 or 100,000 mile plug change. Not sure how true this is. But of course I chose the cheaper of the two:D

    Only time plugs should become an issue of whats best, would be when running a SC... I believe this requires a colder plug, which comes w/the SC Fit Kit...

    Other than that, OEM copper will get the job done, and yes nevermind the NGK/Denso R/L mix match. If you are gunna do it, do it right. Let the dealership worry about pleasing Manufacturer's:cool:
