Ignition Coil and Iridium Spark Plugs for Chevrolet Malibu (2013-2015) 2.5L

Direct-Fit High-Dielectric Ignition Service Kit for 2013-2015 Chevrolet Malibu

Replaces degraded factory ignition coils and fouled plugs to restore spark energy, resolve secondary circuit misfires, and stabilize direct-injected idle performance.

The Stock Malibu Ecotec Ignition Degradation

Under tight underhood packaging on the GM Epsilon II platform, the high-compression 2.5L LCV engine generates elevated cylinder head temperatures. Over time, thermal cycling causes micro-fracturing in the factory epoxy resin and internal copper windings of the coil-on-plug packs. This insulation breakdown induces secondary voltage leakage, intermittent P0300-P0304 misfire codes, hesitations under load, and carbon buildup across fouled standard electrode tips.

The Engineering Solution

This complete ignition overhaul kit features four high-output coil packs engineered with high-conductivity internal copper windings and reinforced thermoplastic housings to resist thermal fatigue. Paired with fine-wire iridium spark plugs, the setup lowers the required ionization voltage, reduces spark quenching, and delivers consistent millijoule output across direct-injection combustion events under peak cylinder pressure.
