I've never seen a replacement just for the coil packs. If you're so inclined, you can purchase new plugs for the coils and create your own replacement. Not very hard BTW. You'll have to splice into the factory harness though as each coil has it's own wire running back to the ECM. I'm assuming you have a '05 to '10GT as I don't know what the engine harness on the Coyotes 11-14 look like.
