On the left side of the engine there is a rail with 3 rectanglular coils. there are 4 bolts attaching it to the cylinder head. remove the 4 bolts and pry it away from the head (if needed pry alternate sides to remove all boots from the spark plugs). If needed there is a connector near the back of the coil rail that can be disconnected by pushing the red slide tab outward then squeezing the tab on the connector while pulling it off the rail. Then remove the spark plugs. insert new ones, reverse steps. Be careful not to use too much force on the slide tab. they break pretty easily although they arent completely necessary.
