    Do not use these. Period.
    These were NOT exact replacement for a 2017 Toyota Camry. They are a full 1/2 shorter than the OEM Densos. Luckily, I kept the Densos until I get exact replacement because they started misfiring from the point I put them in.Also, the ends are weirdly tapered / scraped off by some machine, but the Densos are flat and rectangular like a spark plug electrode should be.Hilarious that these were recommended to me and wasted two hours of my time (putting them in, riding around figuring out this nonsense wouldn't work, taking them out, putting the Densos back in)

    Bought these for my 2003 Thunderbird. All of them were used spark plugs. Useless waste of time. Now I have to return them and go through the pain of re-installing the coil covers and repeating the process all over again.
