What spark plugs do you ford guys suggest to use in a 1969 ford 3400 3cyl. used mostly for plowing snow ?
 
Autolite AG5 was spec from tractor operations. Champion N-14Y is another. These a obsolete numbers.Lots of options today.
 
Im running the new Autolites in my 68 with no complaints, I believe they came with my tuneup kit from here (cap, rotor, wires, points & condenser) turns out my ignition problems were the old wires.
