Ignition Coil and Iridium Spark Plugs for Jeep Renegade (2015-2019) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2019 Jeep Renegade

What it Does: Restores factory secondary ignition voltage and stabilizes spark kernel propagation to eliminate engine misfires, rough idle, and hesitation on the 2.4L MultiAir engine.

The Stock Renegade Ignition Breakdown

Under-hood heat soak in the tight BU chassis engine bay accelerates thermal degradation of the factory coil pack dielectric potting and silicone boots. Over time, high thermal cycling leads to internal insulation breakdown, micro-arcing, and secondary winding resistance drift. Paired with worn factory spark plug electrodes experiencing gap enlargement, the ignition system struggles under MultiAir load transitions, frequently triggering P0300-P0304 cylinder misfire codes, reduced fuel economy, and power loss.

The Engineering Solution

This comprehensive tune-up kit features four high-output ignition coils manufactured with high-purity copper windings, vacuum-poured dielectric epoxy, and heat-stabilized thermoplastic housings that resist high-voltage tracking. Included are four fine-wire iridium spark plugs engineered with laser-welded center electrodes that minimize required firing voltage, provide superior anti-fouling resistance, and maintain precise gap tolerances under severe operational heat cycles.
