MPG Spark Plug Wires 2007-08 Wrangler/Limited 3.8L

Put dielectric grease in for boots to seal and keep them numbered to keep firing order correct.
they are a good replacement for my 5 year old wires.

They are not lying
Well The box doesn't lie. They are truly 0 ohms. The factory Jeep Wrangler jk cables did about 40 ohms. Haven't driven yet to see if it changed mpg or not but I'm deffnatally getting more power with this and Bosch fusion plugs
T**N
