Its not to hard just takes a few hours all 8 coils are bolted down and the support bracket blocking the coil on the left side on the front needs to be removed just two or 3 bolts adn to take that spark plug out you will need a long extension and a medium size extention for your rachet. Be careful bolting back down the coils the bolts are very fragile if its to hard going back in get a new bolt, I broke one of mine 
and had to pay a mechanic to take it out and re do the thread.

You would need either an 8mm or 10mm socket to get the bolt out of the coil(almost positive its an 8mm). Then a 5/8 spark plug socket and obviously new plugs. It took me about 30 mins. But i also used to work at the dealership.
