Hello there

Does anyone know the spark plugs gap for a ST170 :angry::angry: ??

I had a look at the Ford Technical disc (TIS) but cannot find it anywhere. I found the torque for the spark plugs and it's 15NM.

hope to hear from somebody soon.

    Why do you need the gap ? Not being funny but when plugs are bought they are set to specific gaps to give the required air gap for the fuel/air mix to ignite most efficently , further more if you adjust them coatings like silver or irridium coatings can be damaged on the contact surfaces thus increacing resistance across the 2 point which would give delayed combustion
