  • Q:

    Does this have a threaded top? Does the top cap screw off?

      Hi Steve, I'm happy to help! It does not have a threaded top but a loose nut terminal which will include a removable terminal nut placed on the spark plug that can be removed for use in applications which use resistor caps that snap over only the threaded stud.
