Spark Plug Wrench Size?

[sprint99]

Can someone inform me what the size of the spark plug wrench is for my 2000ex? The dealership here in town, believe it or not, is no help in getting me that answer.

And other than the dealer, where did you buy a wrench? I believe I need a thinwall socket..... but need to know size so I can hit the local tool supplier.

Thanks!

Post below states 18mm deep, does the socket need to be thin walled socket?

I use a regular Craftsman 3/8 drive 18mm deep well with no problems. Some say you need a thin wall socket. Mine is about 18 years old though.
