Received these a couple of days ago.They were generally very easy to install. The quality is there, however, quality control wasn’t. Three out of the four coils I had to reassemble.By that I mean, one of them had the spring disconnected, not a big deal reconnecting.Another one three washers on the bolt so I had to remove two of them, again not a big deal.Two of them had the connectors a little bit bent so the conector in my truck would not fit, I had to re arrange them, not much of a big deal hoSee full review
