I've got Iridiums in my '78 ZX that I've turboed, they seem to work pretty well, a bit smoother over the standard plugs and it seems to start a bit easier. They've got the smaller hex size though, I think I put BKR6EIX11s in it, either them or BCPR6EIX11.
Iridium IX plugs for a 79 280zx
Looking into getting these plugs for my 79. But the NGK site only comes up with the standard plugs for this year zx.
NGK says year 80-83 zx's are compatible.
is this bs or what?
anyone ever tried them on a 79-earlier z?
