Ignition Coil and Iridium Spark Plugs for Buick Regal (2014-2017) 2.0L

Direct-Fit Ignition Service Kit for 2014-2017 Buick Regal 2.0L

Restore primary ignition performance: This complete direct-replacement ignition kit renews spark delivery across all four cylinders to eliminate misfires, rough idling, and hesitation under boost.

The Stock Regal Ignition Degradation

The turbocharged 2.0L LTG platform operates under elevated combustion chamber pressures and high thermal loads. Over time, OEM ignition coils suffer from dielectric breakdown, internal micro-arcing within the copper windings, and thermal fatigue in the epoxy potting. Concurrently, factory spark plug electrodes erode, expanding the plug gap and forcing the coil packs to discharge at higher voltages, accelerating secondary circuit failure and triggering intermittent P0300-series trouble codes under high boost.

The Engineering Solution

This ignition pack features reinforced coil-on-plug assemblies engineered with high-conductivity internal copper windings and high-dielectric epoxy housing to resist thermal saturation and prevent electrical leakage. Paired with fine-wire iridium spark plugs that maintain stable gap geometry under high cylinder pressures, this kit delivers consistent spark energy, stabilizes idle quality, and ensures complete flame-front propagation across the entire RPM band.
