Nope. Just put the sparks plugs in, and pop those wires right on! Although, I know that I bought a set of the Accel Superstocks for my F150 a while back, and they didn't come precut, so I had to put them together myself. Just depends on where you get them from, and the availability. Either way, it's a cake job, even if you have to put the wires together, or just pop em' right on. Also, I'm a fan of the Bosch Platinum plugs..That's what I run in my ranger. But that's just me. Lol. Have fun!
