Ignition Coil and Iridium Spark Plugs for Audi A6 (2012-2014) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2012-2014 Audi A6

Primary Function: Restores factory secondary ignition voltage and resolves high-boost misfires by replacing worn coil packs and eroded plugs with heavy-duty copper-wound assemblies and fine-wire iridium spark plugs.

The Stock A6 Thermal Breakdown Weakness

The turbocharged 2.0T EA888 engine in the C7 chassis subjects ignition coils to extreme thermal cycling within recessed cylinder head wells. Over time, heat soak degrades the factory internal epoxy potting and weakens the secondary copper windings, causing spark blow-out under boost and intermittent cold-start misfires. Concurrently, standard spark plug electrodes suffer from gap widening and thermal erosion, increasing the required ionization voltage and triggering P0300-P0304 fault codes.

The Engineering Solution

This kit features reinforced coil-on-plug units engineered with high-purity internal copper windings and high-dielectric insulation to resist internal shorting under thermal load. Paired with laser-welded iridium fine-wire spark plugs, this setup lowers ignition voltage demand, stabilizes flame kernel growth during combustion, and maintains precise electrical conductivity under elevated cylinder pressures.
