Ignition Coil and Iridium Spark Plugs for Buick Regal Sportback (2018-2020) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2018-2020 Buick Regal Sportback

Precision Ignition Overhaul: Restores factory ignition energy, stabilizes combustion under boost, and eliminates misfire-induced limp modes on 2.0L turbocharged models.

The Stock Regal Sportback Coil Degradation

The 2.0L LTG turbo engine subjects factory ignition components to extreme thermal stress and elevated cylinder pressures. Over time, OEM coil pack epoxy degrades from aggressive underhood heat cycling, leading to internal winding short circuits and high-voltage dielectric breakdown. Concurrently, turbocharged direct injection accelerates standard spark plug electrode wear, causing gap widening, carbon tracking, hesitation under load, and random cylinder misfires.

The Engineering Solution

This comprehensive ignition overhaul kit integrates reinforced coil-on-plug assemblies featuring high-grade oxygen-free copper windings and heat-stabilized thermoplastic insulation to prevent arcing. Paired with precision laser-welded iridium spark plugs, the set maintains focused arc propagation under peak boost pressures, ensuring complete combustion, reliable throttle response, and maximum thermal endurance.
