No matter how dang hard i pull they will no come off. I have even tried to use plyers.! it does not work! Any ideas?! Thanks....Changing Ford Ranger spark plugs... Help?Twist the boots untill they pop free, don't pull or twist the wires. Getting something under the end of the boot and pulling up can help too.
