I never had the tool that came with the bike so I use a long 1/4'' drive socket and extension, I stuff a rubber washer up the socket so I can pull out the old plugs once they are unscrewed. I'm careful to remove the washer before screwing in the new plugs though, otherwise the socket stays with the plug and pulls off its extension and thus gets marooned in the plug hole.
