Pepe,
welcome to Automotive Forums..
whether you are in Spain, or the Yucatan; i hope it is warmer there than colorado..
you attached your chat to an older forum post about the gap of a Tacoma that just happens to use the same plug.. on your radiator support/shroud should be a placard with emissions notices and tune-up specs; which will include plug gap.
that being said, the toyota 1.5 and 1.6 engines usually have (you are correct) a 1.1mm; or .044" in america, plug gap.. they might be pre-gapped at .8mm in your area, if another (more popular) Toyota engine that sells more plugs (a V6 or 8cyl) might be gapped at the smaller .8mm (or .032").. hope this helps.
