Ignition Coil and Iridium Spark Plugs for Chevrolet Malibu (2016-2021) 1.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2016-2021 Chevrolet Malibu

Direct-Replacement Ignition Overhaul: Restores factory spark energy and cylinder combustion efficiency across all four cylinders in turbocharged 1.5L applications experiencing misfires, rough idle, or spark blowout under load.

The Stock Malibu Thermal Degradation and Misfire Tendency

The direct-injected, turbocharged Ecotec engine subjects factory ignition components to intense thermal cycling and high cylinder pressures. Over time, OEM coil boots degrade from underhood heat soak, resulting in dielectric breakdown, secondary voltage leakage, and micro-arcing against the cylinder head. Concurrently, factory plug gap erosion increases resistance, forcing the factory coils to work beyond their thermal threshold and triggering P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This complete tune-up kit features heavy-duty coil-on-plug assemblies engineered with high-conductivity internal copper windings and reinforced thermoplastic housings to resist thermal fatigue. Paired with fine-wire iridium-tipped spark plugs, the assembly ensures stable arc discharge, lower required firing voltage, and elevated resistance to fouling under direct-injection carbon load. Precision-formed blade terminals ensure direct plug-and-play communication with the factory powertrain control module without electrical resistance variance.
