      Description

      Superior Power and Performance. Upgrade your Grand Cherokee’s factory coil packs with these high-performance GMS Pro Series Xtreme Coil Packs. They offer voltage up to an incredible 80,000 volts for even more aggressive power and performance. This gives you better throttle response and smoother idle than stock coil packs.

      Improved Fuel Efficiency. Designed for improved performance, these coil packs improve your car’s fuel economy. That’s because they produce a higher voltage, which allows the spark plugs to produce hotter sparks. This results in more efficient burning of air and fuel mixture, which helps in releasing more of the fuel’s potential energy.

      0 OHM Resistance. These Coil Packs feature 0 OHM resistance, which means that they can be used without interfering with your car’s radio and other electrical devices.

      No-Tune Installation. These Coil Packs are designed to improve the performance of Grand Cherokee using its factory tune. However, we recommended performing custom tuning after installation for the best possible results.

      Not CARB Certified. These Coil Packs are not CARB certified at this time. As such, they are not legal in California or other states where California emission standards are being adopted. They may also not be used on pollution controlled cars and are intended for off-road use only.

      Backed by a 90-Day Limited Warranty. To assure quality, GMS guarantees this set of Pro Series Xtreme Coil Packs with a 90-day warranty from the date of purchase of the original buyer. Please note that some exclusions may apply.

      Application. This set of 8 GMS Pro Series Xtreme Coil Packs is designed for 2005-2021 V8 HEMI Jeep Grand Cherokee WK and WK2 Models.

          Word On The Trail

          I appreciate the time your staff took making videos to demonstrate how a product will look on my vehicle as well as how easy/challenging it will be to Install. It is so refreshing to purchase a product from a person/company with actual first hand knowledge of that product. Informed decision equals buyer appreciation/confidence. Thank you.
