It take a little while but their not bad to get at, I do mine in about an hour taking my time.
Stock plugs are Champion RE14MCC4 Copper Plus Plugs. Rockauto has the best price that I found.
Take the wires off the coil packs via quick disconnects. You'll need a 10mm socket/wrench to take off the coil packs (two per pack). Once loose just pull up on the coil packs to remove them. This gives you access to the plugs, 2 per cylinder (16 total).
