    I just bought a 2016 Tundra Limited with 125k on it. I was thinking of replacing the spark plugs soon. What brand is a good brand and I'm assuming iridium is the way to go. Thank you in advance.

    Genuine Denso Iridium. Avoid counterfeit Chinese plugs by passing on Amazon, ebay, and other cheaper places. Get them directly from your Toyota dealer. Pricey, but at least you know the electrodes won't burn off in 30K, and the porcelain won't break off a chunk and ruin a piston/cylinder. Threads in the archive on this.

    If you are not supercharged, get the NGK 94122 LFR6AHX-S Ruthenium HX Plug.

    Check the "Warranty and Maintenance Guide" that came with your truck. Recommended interval may depend on OEM sparkplug originally installed. If equipped with the Denso Iridium SK20HR11 plug shown above, the recommended service interval is 120K miles.

    You don't have to get them from the dealer. A place like AutoZone, Advanced Auto, O'Reilly Ect will have authentic plugs. Just don't buy off if eBay or Amazon. You can usually find coupons for Auto stores too unlike stealerships.

    Counterfeit plugs are a new development, and the parts supply chain hasn't awakened to the risk yet. As the Chinese have discovered, capitalism runs on greed, and that often mixed with dishonesty.

    You have absolutely no evidence that local stores or regional buyers for parts chains will not succumb to the temptation of higher profits if a "no-questions-asked" opportunity seems to present. I would expect "greed" (call it ambition) to kick-in if individuals see an opportunity. And, if not regional buyers, then shady parts distributors that may either knowingly or unknowingly sell fakes to chains and local stores. Amazon buyers aren't dishonest idiots, but they're not smart enough to know the difference either. After close examination of these fake plugs here, I'm not sure experienced buyers and distributors can. These are not crude, obvious replicas.

    I'm not shilling for "stealerships". I wouldn't even trust ALL dealers to not have counterfeit Denso plugs...EXCEPT...that through the Toyota parts network, they can probably get the genuine article as cheap as the Chinese fake. There's little incentive for them, particularly if Toyota gets wind of fake parts being used under their logo. Buy your spark plugs where you want, but I wouldn't recommend any source that could save someone a few bucks now just to cost them thousands in the future.

    My evidence would be that I have bought plugs from auto part stores and did so after much research about fakes. When you buy fake plugs on Amazon and eBay it's very obvious since the plugs are half the price as they should be. Auto part stores are not going to risk their reputation buying fake Chinese plugs. Part stores buy plugs from NGK, or Denso directly, you're telling me AutoZone is contacting the Chinese to sell fakes? You call out my lack evidence to back it up with your lack of evidence. I have bought authentic plugs from AutoZone so that's atleast more evidence than you have to say they sell fakes. All the fakes you see come from eBay and Amazon, not legitimate Auto part stores. Fake plugs are not that new, been around at least a few years now, just most people don't know about it.

    The people have heard the arguments for both sides now. They can decide for themselves. Caveat Emptor.

    A few years ago, I changed the plugs in my brothers 09 Tundra at 140k miles. They still looked new! Probably could have gone another 30k miles. Not like back in the day of getting 10k on the plugs and having to change the points and condenser too. But the sound of my 455 barking while getting 10mpg in town. Them were the days!
