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.

Screamin demon ignition
Just ordered a super-hot ignition coil "Screaming Demon" and awesome 10mm wires to go with it! A friend who is using this set-up reports "only good stuff", incl. a 1 MPG increase. That will get better, but for now he can't keep his foot out of it, running strong! Hope it will do the same for me! If nothing else, it will waterproof the ignition a lot more, because the silicone boots grap like crazy. They withstand heat up to 1,400 F!
Anybody running this set-up?
