    Taking in my 2013 OR for new plugs. 62,000 miles. Had it done at 30,000 miles 18 months ago. Should I get new spark plug wires too? ALso, should I get platinum plugs that last 60,000 miles so I don't have to do this again for at least a couple more years?

    There's no wires. THey are coils and no, you don't need to replace them. And I would advise against anything other than factory copper plugs. I use denso..

    Just curious - 2.7 calls for iridium plugs every 100,000 - why do they call for copper every 30000 0n the 4.0 ? A engine is a engine.

    I can say from personal experience that iridium plugs don't last well in the IGR - somewhere in the neighbourhood of 65,000 KM on mine (roughly 42,009.7256 miles ;) ) and gaps were
    mid 60's. Interestingly enough, the ground electrodes were what was badly eroded, makes me think the coil packs are reverse polarity of other Toyota engines. Our '01 corolla runs iridium, still look pretty good when they have 100,000 km on them.

    I figure there isn't much point to iridium plugs if they are not going to last anyway. Went with Denso coppers for 1/3 the price.

    I put iridium in my 4.0 at 40k miles. Autozone said that was all they had, so they say...... I'm at 55k miles and working just fine. I'll probably order copper online next time though. For the price and how easy it is to change them its no problem to change them at the service interval.

    To use iridium plugs, the electrical system should be designed for them. I use denso plugs only.

    When I took my truck in for its 30k service, per Toyota's own maintenance website, I asked to have the plugs replaced. The service manager said it wasn't necessary. Interestingly, I ended up replacing them myself at about 55k miles, which gave me the time to read up on it on this site, change them myself, and save some money. Thanks, TW.

    Nah. For whatever reason, iridiums were not tested by engineers so Toyota wasn't going to recommend them pre-2014. (Iridiums became std on 4.0's in 2014). I can attest they run fine on earlier 4.0's. I have nearly 90K miles my NGK Iridium IX's. I pulled them out recently to check on them and, against NGK recommendation not to re-gap Iridium plugs, I re-gapped them as I did not have new plugs onhand and needed to get the truck running. 5K miles later, engine is running smooth and, predictably, is more responsive then before the re-gapping. The ground electrode (nickel) is what wore out, causing the wider gap. Got exact results when I checked Iridium plugs on wife's Lexus, which 3.5 came stock with Iridiums. Lexus plugs had about 75K. May get Laser Iridiums or Denso Iridium Tough next time as the ground electrodes have an embedded platinum chip.

    OEM Denso plugs for my Tacoma, I can drive for about 2 1/2 years between changes and the plugs are super cheap online. I got mine off of Amazon.

    toyotapartsdeal.com - online Toyota parts seller in SoCal thinks otherwise:

    Some claim that Super Charged(SC) motors have the Iridiums and I don't doubt that. Looks like the other V6s still have copper plugs.

    You are correct. I used an online vehicle maintenance schedule site (now I can't find it) and it listed 120K mile change for plugs, up from 30K for 2013. That could only be for Iridium plugs. However, I looked up a 2014 Tacoma manual and a Toyota plug sheet and neither shows Iridiums as OEM.

    I remain supportive of using Iridiums for our 4.0 Tacos. I've placed Denso Long Life Iridiums SK20HR11 on my Amazon cart.
