How do you replace coil packs on a 2000 Hyundai Sonata and what do they cost?

I'm not a pro, but i just did this my self and figured i would share. I have a gls v6. after i took off the decorative plastic shield and threw it away, trace the wires from spark plugs back to coil pack. It will be on top driver side of engine. all coils are in one unit. disconnect battery. disconnect all wires from coil pack (be sure to label the wires to save a headache later) its 3 or 4 screws to remove and replace. should be done in less than an hour.
