Check here, as there's a bit of gap (pardon the pun) between S1 and S2-3 requirements.

IIRC S1 petrol are 1.1 and S2-3 are 1.3.

I gap my LPG plugs at 0.9, but the NGK site says 0.8.

But for your own peace of mind and general info, take a lookie at the site.

so you aren't supposed to take them out of the cardboard box and stick them straight in the car??

if the gaps were left how they come what difference would it make to the car?

Close the gap up mate at least 1.1mm Fatter spark = better fuel economy ...

There is a Subaru plug pre-gapped at .8mm the turbo boys use that has had great success in LPG applications and the price is more than half the iridiums...
