If they cover them under warranty then dealer can do it. If not it's a 2 min job to replace yourself. Like this
Remove the Engine Cover - Just pull upwards gently but firmly DONT YANK and it will pop off the 4 Lugs that hold it in place. Also if you have an Aftermarket intake and heat shield remove those aswell. Your Engine will look something like this.
Next remove the 2 Screws that hold the Coil Pack Loom in place. Don't Panic if you don't have them they are not vital
Next Disconnect the Coil Pack loom by pushing the tab down and gently pushing back to the rear of the engine. Do the same for all 4 Connectors.
Next remove coil packs. Just lift up again don't yank and i stored them in the order they came out so that they went back to the same cylinder.
Then just the reverse to put a new one in and put back together
