H-10 Champion spark plugs

What does the C stand for? Early Ford sells Champion H-10 Plugs for $3.50 each. I do not know if they are C's. And Early Ford is in home state. Support your local vendor.
 
Joe, the "C" stands for "copper core" plug. If I remember correctly,the copper core helps the plug to run cooler,to help eliminate pre-ignition from heat. I will call Lou( Early Ford V8) in the morning to see if he might have H-10s in stock. I agree, and do support local and in State vendors. In fact I just recieved an order from Early Ford V8 this evening. They give me the fastest shipping of any Old Ford Parts vendor that I have bought from! Thanks,Tom
