You can now slide the Ecotec strip in the direction of the arrow and lift off - do not force, it lifts off easily.

With the Ecotec strip removed, undo the 2 Coil Pack bolts arrowed, using the Torx Bit.

Ease out the Coil Pack exposing the plug wells (arrowed).
Using the Plug Socket, Extension Bar and Rachet Wrench, remove each plug.

Check the plug gap between the electrode an the contacts - arrowed (it should be 1.00mm)
adjust as nescessary.
Insert each new spark plug into each plug well, locate thread using socket and extension bar,
turning by hand - do not use a wrench at this stage.
Once you are sure each plug is located into it's thread, tighten with the torque wrench to 25 Nm.
Replace the coil pack, firmly clippling it onto each plug, and tighten down, nip tight (do not overtighten).
Slide the Ecotec stip back onto the top of the engine, and re-engage the DisPack until you hear it
click back into place.
Job done!
