They are located under a cover on top of the engine. Depending on the age of the vehicle it will either have 2 screws or 3 8mm bolts holding it on (there are 2 longer bolts and 1 shorter so be careful when refitting). Once removed the HT leads will be visible and to remove these just undo the 4 8mm bolts and pull them
out, then you will be able to access the plugs. Hope this helps.
