    Apparently this is a Corona stain, harmless

    I swapped mine at the same mileage. They looked almost identical to these. Nothing to worry about.

    I am noticing a noticeable increase in power from the engine.
    Eco mode feels like normal now
    Also less noise from the engine

    Fake Chinese knockoffs, it looks like.

    Hope I'm wrong, but the price suggests otherwise.

    It's not just fleabay.
    Amazon has a biiiiig problem with fakery too.

    Given how hard they are to get to and how long they (are SUPPOSED to) last this is one of the few times that I would go with dealer stock or one of the big suppliers.

    YMMV

    so you’re saying Bosch plugs guarantees that plugs will stay original color under the same oci?

    No, counterfeit problems.......
    On the 2nd set. When I pulled the 1st set out I couldn't tell if there was any wear.
    They all get discolored from the heat. But nothing abnormal.

    No, these came in just like original with the Denso and Japan inscribed in the metal. Also they came in a toyota lexus box. They alaso had a plastic sleeve on top of the plug to protect the firing element. Quite comfortable that these were original
