When you open the hood you'll notice your valve cover says 16 Valve, and DOHC on either side of the cam cover. Between these two words is a cover, which goes over the spark plug wires. Once you remove the cover, and the spark plug wires, the spark plugs will be revealed.
Lift the hood, disconnect the battery, remove the spark plug cables and covers, and remove the old spark plugs. Next put in the new spark plugs, replace the cables and covers, reconnect the battery and close the hood.
