Autolite Champion AC Atlas Motorcraft Auburn Spark Plug

These are the old style copper core spark plugs. Why Copper vs Platinum vs Iridium, Copper is just a better conductor of electricity than the other two. The only drawback is they should be changed every 30,000 miles instead of 60,00 miles and do you really think you are going to put another 30,000 miles on this vehicle. 

 

Proper spark plug torque is very important especially with aluminum heads or tapered seat spark plugs as damage can be  caused by over tightening. If you are not sure what the spark plug  torque should be you will find simple instructions and a chart on this site  in articles.

I have identified this spark plug to the best of my ability but do not guarantee anything except you will get the same number spark plug that is listed.  I think these Mighty spark plugs were made sometime in the 1960's and probably fit many earlier models not listed below
