Ignition Coil and Iridium Spark Plugs for Chrysler Cirrus (2007-2008) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2007-2008 Chrysler Cirrus

Ignition Overhaul Package: Direct-replacement set of six coil-on-plug assemblies and six fine-wire iridium spark plugs engineered to restore secondary ignition energy and eliminate cylinder misfires on the 3.5L V6.

The Stock Cirrus Secondary Ignition Breakdown

Under sustained thermal cycling within the transverse JS engine bay, factory coil epoxy degrades and internal primary/secondary copper windings develop micro-shorts. This dielectric breakdown leads to high-voltage leakage, reduced spark arc duration, cold-start hesitation, and intermittent P0300–P0306 misfire codes under heavy engine load.

The Engineering Solution

This matched overhaul kit combines high-grade internal copper coil windings with thermoplastic boots that resist thermal breakdown at elevated cylinder head temperatures. Paired with high-melting-point fine-wire iridium electrode spark plugs, this system maintains a consistent, high-energy spark kernel across the entire RPM range, preventing plug fouling and stabilizing air-fuel combustion.
