A drain plug for a spark plug? Now why would there be? What would you drain from a spark plug.... the spark? If you're referring to a plug for the spark plug socket, I'm sure you could find something that would fit that would keep out debris while you let you engine sit without plugs. (Why??)

bad spark plug wire.
