Not sure about the part number, but the plugs are really easy to fit.
Just pop of the plastic engine cover, just twist the little plastic screws quarter of a turn and then you can pull the cover off.
Depending on which coil packs you have they either just pull off (like mine) or the older style ones have 2 allen key bolts holding them in.
The plugs then unscrew easily with a spark plug tool.
When putting the new plugs in its best to push the plug into a bit off rubber hose and then screw them into the hole and make them finger tight, then use the spark plug tool to tighten them. By using the hose it stops you accidently cross threading the plugs in the block!
