REMOVAL

NOTE: On some later models engines, removal of engine air intake plenum and other components will be necessary.

1. Always keep track of the spark plug cable routing and plug wire bracket locations. Number the spark wires so that you won't cross them when you replace them.
2. Remove the wire from the end of the spark plug by grasping the wire by the rubber boot. If the boot sticks to the plug, remove it by twisting and pulling at the same time. DO NOT pull wire itself or you will damage the core.
3. Use a spark plug socket or equivalent to loosen all of the plugs about two turns.

   NOTE: Remove the spark plugs when the engine is cold, if possible, to prevent damage to the threads. If removal of the plugs is difficult, apply a few drops of penetrating oil or silicone spray to the area around the base of the plug, and allow it a few minutes to work.

4. If compressed air is available, apply it to the area around the spark plug holes. Otherwise, use a rag or a brush to clean the area. Be careful not to allow any foreign material to drop into the spark plug holes.
5. Remove the plugs by unscrewing them the rest of the way from the engine.
