Spark Plug gap on 940
 

Can anyone tell me what the correct spark plug gap measurment is on a 2.0 1991 940. Enging code b200ft

0.7-0.8mm

What he said! ^^^^^

Don't be fooled into thinking new plugs come set at the right gap, the default gap on a new NGK is 0.9mm for example so needs closing slightly.

As the gap opens over distance driven, i'd set the gap on new ones at 0.7mm, gives more of a chance on a cold start. ;) :D
