In short, the number depends on the engine: the 2017 Cherokee uses four ignition coils with the 2.4L four-cylinder, and six with the 3.2L V6.
The 2017 Cherokee offered two primary engines in most markets—the 2.4-liter Tigershark inline-four and the 3.2-liter Pentastar V6—each using a coil-on-plug arrangement. The total coil count equals the number of cylinders in the chosen engine, so coil counts vary by configuration.
Engine options and ignition coil counts
Below are the configurations most commonly found in 2017 Cherokees, showing how many ignition coils each engine uses.
- 2.4L Tigershark I4: 4 ignition coils (one per cylinder).
- 3.2L Pentastar V6: 6 ignition coils (one per cylinder).
For diagnosis or repair, confirm your exact engine to ensure you source the correct coil-on-plug assemblies and related wiring.
Practical implications for maintenance and troubleshooting
Knowing the coil count helps with misfire diagnostics, part ordering, and wiring harness checks. When a 2017 Cherokee misfires, you should identify which engine you have to determine how many coils to test and replace.
How to verify your engine configuration
Check the vehicle identification number (VIN) or look under the hood for the engine label. If the label reads 2.4L or "Tigershark," you have 4 coils; if it reads 3.2L, you have 6 coils.
Summary
In the 2017 Jeep Cherokee, ignition coil count aligns with engine displacement: four coils on the 2.4L four-cylinder, and six coils on the 3.2L V6. Always verify engine type via VIN or labeling to confirm the exact configuration for maintenance or part replacement.
