Faster starting, smoother running, more power! You will be amazed at the improvement this kit will make in your vehicle. Your rig will start faster, run smoother, and have more power and better fuel economy too. This ignition kit consists of Performance Distributors' LIVE WIRE plug wires, Screamin' Demon coil, brass terminal cap and rotor. The Screamin' Demon coil allows you to run an astounding .065 sparkplug gap, which gives you a much more powerful burn of your fuel mixture yielding increased horsepower and fuel economy.
This Coil pack is a screamin deal for the gains you get !! Smooth idle, Smoother shifting more pick up !!

Quicker start up, and more responsive throttle.

Good wires, not sure about the coil pack
I have 129,000 on my '09 JK and needed to replace the wires. This wire set is top shelf. custom length, factory crimps, numbered, high temp covering, look good, should easily last another 100+
I also replaced the plugs with Autolite double platinum and gapped them to .065 as directed to do in the coil pack instructions.
After 3 tanks of fuel I see no improvement in fuel economy. I run a 4" rancho lift and 35" KM2's so 15 is about as good as I can get in everyday driving. So far there is no improvement on that number.
Additionally there is no "seat of the pants" detectable improvement in performance.
If you need wires I would highly recommend these wires. They are only about $20 more than the Mopar set and they are well worth the money.
I cannot recommend the coil pack unless possibly you have a bad coil and need to replace it anyway.

To early to tell
Seems to run smooth but I have noticed the engine stumble several times at idle after driving for ten minutes, sometime worse than other times. I have not increased the spark plug gap to .065 yet, so maybe this will help. If not, it may just be a faulty unit.

Immediately after I started driving with this kit on, I definitely notice that the throttle response gap was completely gone. Acceleration seems to have improved more, but the most noticeable thing is the lag being nonexistent now.

Needed more fire
Really just gives better throttle response when you need to gun it,it's there!!
