Hi there, if you go into the local parts shop they will tell you, I don't know off the top of my head but my wife has a car the same and I changed them recenlty using a spark plug socket and extension bar I will have a look at what size the Spark plug socket was.

The spark plugs are 10mm (the size refers to the diameter of the threaded part not the top) and so you need the appropriate sized spark plug socket. It will be called a "10mm spark plug socket".

I found a length of rubber tube very useful. Once the plug is loose, you can push this over the spark plug insulator and lift the plug out. IT can also be used to place the new plugs in place and start the thread. Then you can use the plug spanner to tighten the new plugs
hope this helps
