Mopar Ignition Coil Pack for 00-06 Jeep Wrangler TJ, TJ Unlimited & Cherokee XJ with 4.0L

If you have tried getting more power back into your Jeep I-6 engine by regular tune-up methods of changing sparks plugs and air filters, but still seem to come up short, replace the Ignition Coil with a Mopar replacement and give the engine the spark that it needs to perform. The coil rail is what delivers the current to the spark plug, over time the rail will put out less power and the spark that is created is not enough to do the job. At that point you are wasting fuel as well because some is not being ignited. Restore your Jeeps power and fuel economy with a new ignition coil.
