They're working very well the vehicle starts up on one turn. The vehicle idles nice too.

I have a 96 f 350 with a 460 engine. It has exhaust issues where the heads meet the exhaust headers. The regular wires and even the high temperature wires would burn through the spark plug wires and then it would misfire. The new ceramic wires solved that problem and the truck runs like new again.
