Spark plug tool should be in the tool kit. Not sure of size. Two flat blade screwdrivers, one at the top and bottom and lever the cap off by using the valve cover as a pivot point and pushing on the screwdriver handles. Bob's your uncle. Bottom plug cap just pulls off.

Some toolkits have a plastic cap removal tool, mine had and it never worked. The screwdriver idea does work OK, and all you need to do is just unseat the cap, and then work it free with your fingers. Watch the position of the screwdrivers though, if the are too close to the edge of the plug cap, or you apply too much pressure, you're likely to break off some of the plastic on the insulator.

Also watch that you have the correct plug removal tool i.e. one with the correct and very narrow extrnal diameter. If not, getting the bottom plugs out might be OK, but you can fool yourself into thinking that on refitting that the plugs are fully home. If the plug removal tool is a little on the large side (external diameter), you may think that the plug is seated properly, but it's also might just be the tool getting stuck inside the aperture in the cylinder head, and the plug itself may be a couple of turns short of having a gas tight seal.

You may find it somewhere else and cheaper but this was just a quick search. The plug spanner is 16mm or 5/8''.
