This is what was included in the N tool kit for removing spark plugs and cylinder head nuts:
You can find them on eBay for about $10 - they are fairly common. Can get lucky and find them at yard sales or flea markets for less.
Or, as already mentioned, you can use a standard spark plug socket and ratchet.
