Changing the Oxygen Sensors was the easiest thing I did on my Boxster, perhaps other than changing the MAF. DON'T GET A DEALER/INDY TO DO IT. Even the best indy shops in my town charged way too much for them. Shop around online and you will get a good deal, I got Bosch ones to be safe since they are OEM.
If you want some directions and photos to help you navigate through the procedure, just do a quick Google search and you will find plenty of guides.
