Ignition Coil and Iridium Spark Plugs for Chrysler Cirrus (2008-2010) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2008-2010 Chrysler Cirrus

What it Does: Restores factory secondary ignition output and combustion efficiency across all four cylinders by replacing degraded factory coil-on-plug units and worn spark plugs.

The Stock Cirrus Thermal Degradation and Misfire Vulnerability

The GEMA 2.4L engine's compact cylinder head layout subjects the factory coil packs to prolonged thermal cycling and dielectric breakdown. Over time, internal primary and secondary copper windings develop micro-shorts, causing intermittent high-rpm misfires, rough idle, and unburned hydrocarbon blow-by that damages catalytic converters. Additionally, factory standard spark plug electrodes erode, widening the spark gap and overworking the internal ignition drivers.

The Engineering Solution

This complete tune-up package features four heavy-duty coil-on-plug assemblies engineered with high-grade internal copper windings and reinforced dielectric epoxy housings to resist thermal breakdown and voltage leakage. Paired with fine-wire iridium spark plugs, the kit delivers lower required firing voltage, superior flame kernel expansion, and stable arc generation under high cylinder pressures. Direct-fit blade terminals and factory-matched electrical connectors ensure plug-and-play installation without wire harness modification.
