Ignition Coil + Iridium Spark Plugs for Dodge Stealth (1991-1996) 3.0L

High-Conductivity Ignition Coil and Iridium Spark Plug Kit for 1991-1996 Dodge Stealth

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores primary ignition energy and stabilizes flame kernel propagation on the 1991-1996 Dodge Stealth to eliminate misfires and maximize combustion efficiency.

The Stock Dodge Stealth Thermal Breakdown & Secondary Voltage Drop

Under the compact hood of the Z16A and Z15A chassis, the transverse 6G72 V6 engine creates severe thermal constraints within the cylinder head valley. Over time, the factory coil packs endure continuous thermal cycling, which breaks down the internal winding insulation and degrades the potting compound. This leads to internal arcing, high secondary winding resistance, and high-RPM spark blowout under load. Furthermore, aging conventional copper or platinum spark plugs exhibit rapid electrode erosion, expanding the plug gap beyond factory tolerances and forcing degraded ignition coils to work past their dielectric breakdown limits.

The Engineering Solution

This comprehensive kit replaces high-mileage ignition components with three direct-fit, waste-spark ignition coils and six fine-wire iridium spark plugs. The replacement coils feature high-grade magnetic steel cores paired with reinforced epoxy encapsulation to resist heat soak, mechanical vibration, and insulation breakdown. The included laser-welded iridium spark plugs feature a minimal 0.6mm center electrode diameter, drastically lowering the required ionization voltage across the gap while providing superior wear resistance against spark erosion. Together, they ensure complete flame front propagation, stabilized idle quality, and crisp throttle response even under aggressive cylinder pressures.

Frequently Asked Questions

Does this fit the Z16A Stealth?
Yes, this is a direct fit for the 1991-1996 Dodge Stealth equipped with the 6G72 engine.

Do I need to adjust the gap on the iridium spark plugs prior to installation?
No, the iridium center electrodes are factory pre-gapped and delicate; manual gapping can fracture the fine iridium tip.

The Dodge JDM-Era Caliber

Engineered for high-revving 1990s Japanese-American sports icons, this ignition set preserves peak combustion pressure to maximize high-RPM horsepower, sharpen transient boost and throttle response, and maintain crisp exhaust acoustic dynamics.
