Product ReviewsSpark Plug-Copper Resistor Autolite 46

Excellent Quality

I purchased these to replace the worn out spark plugs (Autolite BF82) on my 1949 Caterpillar D4 tractor's starting engine. The plugs I purchased were in excellent shape, and they do fit the starting engine quite well. I have yet to test them (the starting engine needs an oil change, and I haven't had time to do that or gap the plugs), but based on visuals alone, I have no doubt they will work very well.

Autolite spark plugs

I bought these for use down the line. I would think that they are of good quality being Autolite.

Autolite spark plugs 46.

Autolite spark plugs run very well in my 1979 Mercury Zephyr vs Motorcraft BSF-82.
Hands down 3 times better running little hotter plug.
