This thread is more than a year and a half old, and Larry has updated his spark plug recommendations slightly since then.

See the link above on Ford Garage for his most recent spark plug list for 7/8-18 spark plugs for Model A and B engines.

I just purchased a set of W18's. I have c16c's in the motor now. the W18's are bigger in size. Did I get the right plugs?

You will like the W-18's, which is the closest replacement for the C16C plugs. They might look bigger, but that is only the part that is above the head.
