They are 12mm plugs and require an 18mm socket.
i've never owned a gw before
and thought the standard gw ngk
spark plugs were a standard spark
plug width 14mm.
i've tried three spark plug sockets,
none fit the rusty little critters?
please can anyone advise me of
the correct spark plug width etc.
is this a special tool by honda?
I thought that's what you wanted, any how, any late model car plug socket will work!!
