Ignition Coil and Iridium Spark Plugs for Buick Regal (2011-2013) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2011-2013 Buick Regal

Replaces degraded factory ignition components: Restores primary and secondary spark energy delivery across high-boost operating conditions on GM turbocharged engines.

The Stock Regal Ignition Coil Insulation Breakdown

Under elevated cylinder pressures and continuous thermal cycling, the OEM ignition coils on the Regal turbo platform suffer dielectric insulation fatigue. Radiated engine bay heat degrades the internal epoxy potting, causing internal winding resistance shifts and high-load secondary arcing. This results in misfire codes (P0300-P0304), sluggish boost onset, and rough idle characteristics.

The Engineering Solution

This direct-replacement kit features coil-on-plug assemblies engineered with high-grade copper primary and secondary windings encased in high-dielectric epoxy housing. Paired with fine-wire iridium spark plugs engineered to withstand severe combustion temperatures, this assembly ensures minimal quenching, low firing voltage requirements, and reliable flame propagation under full turbo boost.
