    Its 0.8mm (0.032"), use NGK plugs.

    Good luck !

    If you obtain the correct plugs they should be pre-gapped.
    plus I though all Toyotas with electronic ignition were 0.044" ie "11" coded in the plug.

    maybe not,

    you can't presume the gap is correct!

    True, I had a quick look over the truck and it uses 0.8mm, non-pregapped plugs. The camry uses 1.1mm and pregapped. Interesting. I'll assume there is no label inside the engine bay to indicate the recommended plugs, gaps, Static timing, vacuum hose routing etc.

    Pity, it's something that's used here which avoids a lot of grief and bad running due to mis routed vac hoses.

    So I'll defer to the 0.8mm setting.

    An interesting note; I had at one time replaced the OEM plugs in the truck with Bosch, no problems. However, when I replaced the OEM's in the Camry, it gave trouble at idle, when I replaced them again with the OEM's problem went away.

    Good luck.
