spark plugs
ON the top of the engine, near the front, there are 4 thick blak rubber wires clipped into a harness and on the end of each there is a long plastic part that seem to go down into the engine. If you pull one of these plastic boots out it will expose the spark plug. I hope that's some help, it's difficult to describe really and I'm not sure how different each engine model is but the location should be roughly the same. I don't know what you need to know this for but if you don't know how to locate the plugs then maybe you should let someone else fiddle with them, it is possible to snap them in to with the bottom part stuck in the engine block.
