The spark plugs are very straight forward. Just remove the plastic air tube, then the plastic cover in the center of the valve cover. the spark plugs require a 5/8 socket & 6" extension.
The fuel filter is under the car & requires removal of another plastic cover. Fuel will come out when replacing the filter SO you must be very careful.
