As the spark plugs in your engine get older, they start to get out of shape, wear down and lose the ability to produce as much spark as they once did. When this happens, you will want to replace all of the plugs at once to make sure your engine is functioning at maximum efficiency. Fortunately, changing out the spark plugs is an easy task, and it should take under an hour to replace all of them.
Step 1 - Open the hood and look at the top of the engine where the spark plug wires run into the cylinder head. Grip the boot on the spark plug wire to the far left with your hand and twist it in place on the cylinder head. Then pull it out of the head and place it to the side.
Step 2 - Remove the spark plug from the engine with the ratchet, extension and spark-plug socket. Throw out the old plug.
Step 3 - Use the spark plug gapping tool to gap the replacement plug to 0.060 inch (six hundreths of an inch). Then install the plug into the stock location with the ratchet, extension and spark plug socket. Push the spark plug wire back onto the plug. When it clicks in place, it's locked onto the plug properly.
Step 4 - Repeat steps 1 through 3, moving from left to right across the cylinder head until they are all replaced.
TIPS: Replace one spark plug at a time, that way you don't get confused and cross any wires.
