Ok you will need a ratchet and plug socket 5/8 and swivel and extention. Now it is not easy so do it when it is cold. Move any hoses out of the way and remove spark plug wire from plug and remove plug, install new plug and plug wire and move to the next plug. I know it it tight but that is just how it is there is no quick trick. Before remove plug wire from plug turn back and forth before pulling and pull it off by the boot not the wire if it is hard to reach then buy a spark plug wire pliers. See Pic.
