    What replacement plugs are you folks running out there? I am thinking about Iridium
    $39 NGK LFR6AIX-11 - 6 PCSNEW
    NGK LFR6AIX-11. The users manual is specific about replacement plugs, but various
    sources say these are ok to use, any thoughts or suggestions?

    I just stick with the factory copper plugs.
    Denso K20HR-U11

    My truck is very modded as well, and I have zero issues with the copper plugs.

    I use the irridium. Have had them in for 31k miles and so far so good.

    I don't care to have to changer copper plugs every 30K when I dont have to

    I installed Denso iridiums in all of my Tacomas. They're cost effective and they work. Not designer or snake oil-ish, they just do the job.

    What I have heard is that not using the copper plugs and changing every 30k miles voids the emissions warranty, which I think is to 90k miles. Not sure if that is true, but just in case . . . I just stick with the stock Denso/NGK plugs since there is other maintenance going on every 30k miles. Easy to do, easy to remember, cheap, works great, and you know you've got good plugs.

    I actually just installed these in my truck yesterday. Stock plugs made it to 103k and look like they could have did 20k more. Truck feels a little more peppy and no issues with install. Good luck with your choice but the ones you specifically named seem fine.

    I recently swapped out my Tacos plugs at 39.5k miles. They looked decent but I was concerned with them since my trucks prior life was rough. I followed advice here and just replaced with denso plugs from the dealer. Hope it helps.

    Wait, you ran stock plugs on a V6 for over 100k miles?

    I bought the truck in april with 94k on it. Changed them yesterday at 103k. Had Denso on pass. side and NGK on driver side, so I assume it was still the stock set up. Plugs actually looked pretty damn good if they were indeed the stockers.

    That's what I have in my Taco and coming up on 96K with them. At 80K I took them out for inspection and the ground electrodes were quite worn out, to about .055'ish; gap should be .043. NGK recommends against re-gapping Iridium plugs, but I had no choice as I had no replacements on hand. I re-gapped and installed, and the engine be running as smooth as ever. I now have
    $53 Denso SK20HR11 ---- IRIDIUM PLATINUM power pack Spark Plugs -- # 3421 ----- 6 PCS NEW
    Denso SK20HR11 on hand to replace the NGK's. These Denso's have a platinum tip electrode to reduce wear.

    BTW, those same NGK Iridiums came stock on wife's Lexus ES350 and recommended plug change is 120K. I replaced them at 118K and have same ones on hand for replacement at 200K.
