The engine in the Toyota Avalon has six spark plugs, located on each side of the engine block. On the top rear of the engine is the distributor cap. This component is what powers the spark plugs. To replace them, follow the wire leading from the distributor cap to each spark plug. You will need a few tools and about 30 minutes to gap each plug and install them.

Open the Avalon's bonnet and allow the engine to cool completely. Follow the wire on the top of the distributor cap to the side of the engine and spark plugs.
Pull the rubber wire off of one spark plug. Remove the plug with the ratchet and socket.
Place the gapping tool between the pin and the arm at the top of the plug. Turn the gap tool until the number .034 is in the centre of the gap tool. Insert the plug into the engine and tighten it. Replace the wire to the new plug. Repeat for all the other plugs.
