    Anyone, are these the correct ones for tunes 1991 tt as they are slightly colder than they recommend on the site.

    Thanks.

    stick with the recommended plugs: PFR6B-11B

    Nissan partnr. 22401-40P66

     

    problem with most iridium plugs for the Zed (the right one being the PFR6B-11B plug):

    and for example, this is a socalled 300ZX iridium plug in a TT head:

    There are iridium spark plugs especially made for the VG30DETT available in Japan, but they are VERY rare and I very much doubt sparkplugs.co.uk has these (in stock.)

    just to confirm - I had a chat with the tech guys at NGK UK a few years back & they advised not to use Iridium on the zed & did not list any that were compatible.

     

    stick with plats IMO :)
