I own a 2003 Ford F-150 with a 4.6 motor with 65,000 -+ miles. I would like to replace the spark plugs . How hard of A job to do?? I had Ford `99 F -150 with a 4.6 motor and I replaced the plugs, seem like they were down low in motor . Had to use a extension to do, will the 2003 be the same ???? THAN YOU....
