After reading all the stuff here on the clips, I went down to the toyota dealer brand new dealership a mile away and picked up the factory OEM ones. they were 65 and some change,BUT I ripped the old ones off and had the new ones on in about 10 min. they have the coil clips and they even come with the wires already in the loom clips it is a no brainer.....
