Warranty & Shipping
Product Reviews
Vehicle Fit

The ignition coil pack is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time and cause a misfire condition. In engines like this that use a coil pack, if one coil goes bad, the complete assembly needs to be replaced.

This Ignition Coil pack features the following specifications:

  • New not remanufactured
  • Replaces dealer part numbers: 56041476AB, 56041476AA

Jeep GC running rough...not anymore.
My Jeep GC was throwing a code indicating a #6 misfire. The new coil pack was the fix it needed. Now runs great and has 146000 miles. That Jeep 4.0 is a great engine.
