Ignition Coil and Iridium Spark Plugs for Buick Verano (2012-2017) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2012-2017 Buick Verano

What it Does: Restores factory ignition energy and combustion efficiency across all cylinders to eliminate rough idling, hesitation, and spark misfire codes.

The Stock Verano Ignition Degradation

The direct-injected 2.4L Ecotec engine subjects factory ignition coils to elevated underhood thermal cycles and high cylinder head temperatures. Over time, OEM coil epoxy insulation breaks down, causing dielectric leakage, internal secondary winding resistance shifts, and subsequent P0300-P0304 misfire DTCs. Paired with worn factory plugs experiencing gap erosion, weak arc voltage degrades flame kernel development, triggering poor fuel atomization and reduced low-end torque.

The Engineering Solution

This service kit features heavy-duty coil-on-plug assemblies engineered with high-conductivity copper secondary windings and high-dielectric epoxy potting to withstand continuous thermal saturation. The integrated blade terminals guarantee low-resistance contact with the factory harness. Matched with fine-wire iridium spark plugs, this setup delivers consistent spark kernel formation, optimized flame propagation, and stabilized dwell performance under high cylinder pressures without premature thermal breakdown.
