Disconnect the spark plug lead. Then, clean the area around the spark plug to avoid getting debris in the combustion chamber when you remove the plug.

Clean oily deposits from the plug with a stiff tooth brush and some neat petrol.

Check that the centre electrode is square and is gapped according to the owner’s manual. Reinstall plug being careful not to over tighten.


If you would like to purchase a new spark plug, please contact one of our service advisors. The correct spark plug type must be used or engine damage may occur.
