Honda does not sell a kit. The plugs are sold individually. The slide hammer is the same as a dent puller but instead of a hook, it has a screw installed at the tip, usually sheet metal. If you tap the hole in the plug, the sheet metal screw may work or you will need to replace it with a screw of the same size as the tap. It doesn't take much to pull the plugs but the location and the fact that it is flush with the manifold requires the use of a puller. I made mine using a foot of 5/16 allthread, a couple of nuts and a weight with a hole big enough for the allthread. I mounted the screw at the end of the allthread with one of the nuts and a drilled threaded plug to keep the screw inside the nut. It would be so much easier to use pictures but I don't know how to do that.
