You guys make it seem so much more complicated than it actually is. No tool is required, coils pop out with a screwdriver easily. The only difficult part is getting your hand to the other side of the coil to pull up as you use the screwdriver to apply even pressure
Only tools I would say are required is a spark plug socket, torque wrench, and a variety of extention/swivel
Here are my coils after 25k miles. My gas mileage was around 12 before the change.
