Nah, it's easy! There are no parts that need to be removed for the job.
First lay out the new wires out on a table, and one by one pull one of the old wires off and match it's length to the corresponding new one. The wires just pull off at both the plug end and the coil end- just grab the rubber boot and twist a little until it pops off. Pay attention to the routing from the coil to the spark plug. most of the wires have clips that hold them apart.
The big thing is to make sure that each post on the coil gets reconnected to the same spark plug that it was before. Doing the wires one at a time makes that easy.
How long has it been since the plugs were gapped or changed?
