    I just replaced my spark plugs with some iridium ngks today...Hat tip to chris4x4 for his helpful how-to thread.

    To my untrained eye everything looked good except perhaps the drivers' side rear.

    Not sure how the cylinders are numbered so I did:

    (front of car)
    Driver Passenger
    4 1
    5 2
    6 3
    (rear of car)

    driver side front

    driver side middle:

    driver side rear:

    driver side rear again...

    Edit: Feel free to guess how many miles are on these plugs...

    I say the plugs look good, but drivers rear is showing signs of burning some oil. Ground electrodes are worn and centers are alittle rounded so I would say that there is alot of miles on them. My .02c worth.

    I was going to say around 50K miles. You can certainly tell there are more than the recommended 30K.

    Mostly stock for now, I have added a cb radio, various cheap mods and I plan on adding aftermarket wheels and other items in the future.
    Yes, I have been noticing this too on TW.
    I just did my plugs and saw the same thing. I wouldn't worry too much about it.

    Hrmm I wonder why that is?

    My new iridium plugs are good for 100,000 miles, but I plan on checking the driver's rear plug every 30k, and a random passenger side every 30k just to make a comparison.

    Just a little financing note for you guys: My dealer wanted $169 to change my plugs. Since my iridiums costed $45, $5 for grease, and normally you should change your platinums every 30k, that means I saved $169*3-$50 = $457. Took about an hour. Time to buy a new toy

    Keep an eye on your performance. I have had poor performance with all the Iridium plugs I have tried in the Toyota V6 engines. Seems the OEM Denso copper/nickle plugs give best performance.

    Update: I've put about 5000 miles on my new plugs in the last few months and no noticeable performance issues or mpg issues.

    just a couple comfort items.
    And you trust the monkeys that ship to the parts store not to throw those boxes like their x girlfriends??? I always at least check them, and most of the time there are a couple that are as much as .020 out.

    all plugs are gapped....most nowadays come pregapped to a specified amount, but it's always good to check to what they should be. the double plats i bought were pregapped, but 2-3 were off out of the 6
