You might want to check for a decimal point in there...
Your's will probably be a little different than mine since I have an '86 EA82, but my gap is 0.040 inches which is 1.02 mm.
I think you might mean 0.7, 0.8, 0.9 or 1.4mm.
Beyond that I'm, not sure exactly what gap you are supposed to have.

hi
yes, i was wrong, I mean 0.7, 0.8, 0.9 or 1.4mm.
it's imazing because no one knows for 100% what the sparkplugs gap should be.

maby someone can help me?
i've been told that for best performance i need to make it 0.7mm, is it true?
what will make a small or bigger gap ?
the car is leone 1600cc year 1993 with carb.

thank you all.
moshe.

It's a 1600cc as in the EA71 right? If it is the gap should be 1.0-1.1mm

Be cool Phish, we all have to learn some time, and one way is to ask questions. That's part of why we exist.


But it wouldn't hurt you, Moshe, to buy a repair manual.

Hey, everyone here is giving you the information from US market repair manuals including the factory manuals from subaru. Oh if you have an EA82 then it's a 1800cc engine and it also has the same 1.0-1.1mm plug gap as I mentioned earlier.

The spark plug gap has more to do with the coil and the spark plug wires than anything else. Wider gaps need higher voltages generated by the coil and conducted by the wires. The higher the voltage, the more energy in the spark, and the greater the chance of successfully igniting the fuel and air mixture.

If you have a similar ignition system to what is installed on US-version Subarus, then the gap should be similar. The suggested 1.0-1.1mm should be good.
