Make sure that the engine is cold before you begin. First disconnect the harness that leads to the spark plug cover, located to the right next to the fuel lines. You have to remove the plastic pin and then unplug the wire. Then you remove the four black bolts that hold done the cover, after removing the bolts you have to pull the cover off, it will be tough to pull because it is attached to the four spark-plugs. you may have to push the for mentioned fuel lines to the side a little to remove the cover. Once clear, you will see the four spark plugs. Now the spark plug boot may have remained on the spark plug, just pull it off and put it back on the spark plug cover. Now remove the old spark plugs and install the new ones, the gap for that engine is .050inch All that is left to do is the reverse of what you did before. Hand tighten the four bolts is fine. hope that helps. Its really not that hard. ItsJustMe.
