If you aren't familiar with basic auto maintenance, I'd recommend you have an experienced buddy help with the job. A miss aligned plug(always turn'em in by hand 2 full turns) can ruin the threads. Good luck =^ )
It does make it easier to remove the fuel rail then remove the spark plugs. It is a pretty simple task. You should be able to do it on your own as long as you know how to turn a wrench and don't over tighten them.
