PLUG EXTRACTION 101
Many Toyotas and Hondas have spark plug tubes on their cylinder heads. When these heads get over heated, it can melt the spark plug boot in the tube. Some of these tubes do not come off. There is a way to get the boot out quickly and easily. With the cylinder head removed from the vehicle, break off the bottom of the spark plug. Find a tap that you can start to thread into the bottom of the spark plug. By screwing this in from the combustion chamber side, you will unscrew the plug from the head. With the plug free, it will be easier to pull it and the plug wire free from the spark plug tubes.
