So the autolites are new. Those 2 plugs fouled once already so I cleaned them and reinstalled in the 2 same cylinders and they look like that now. Is the heat range a bit different on the ngks?I don't know if you're cleaning the plugs and returning them to the same cylinders or are you using new plugs that keep fouling in the same cylinders?
The reason I ask is about a year ago I had 3 Autolite 85's foul out like yours at three different times on two different cars.
I switched to NGK plugs and never had a plug foul on either car since I changed brands.
I asked around and nobody else seemed to be having the same problem with the Autolites.
