If you have the original tool kit you will have a long reach plug removing spanner therin.

The plugs are located deep down in the middle of the engine and are accessible down tubes once you remove the caps which run along the centre of the cam cover or top of engine. You will need to remove the airbox on top of the engine to gain acces to them all.

Replace them with the appropriate new plugs and do not over tighten. You may be advised to change the leads at the same time unless they have been done recently.
