I changed mine myself. It took about an hour. I consider myself a better-than-average shadetree mechanic. Access to some of plugs requires various extensions and/or univeral joints, and/or removing some ancillary compenents. A torque wrench is a good idea to assure that the plugs are properly seated and to avoid stripping threads. Apply some never-seize lubricant to the threads to avoid them seizing before next replacement. I personally chose to go with double platinums (a buck or two each more than coppers) to avoid ever having to replace them again in my lifetime. Your lifetime may be different! LOL
