The coil pack is a crucial component of the ignition system in your 2001 Jeep Cherokee. It's responsible for delivering the high-voltage spark needed to ignite the fuel in your engine's cylinders. Upgrading your coil pack can lead to improved performance, better fuel economy, and smoother engine operation.

Coil Pack Specifications

The 2001 Jeep Cherokee uses a single coil pack for its 4.0L inline-six engine.
