Ignition Coil and Iridium Spark Plugs for Audi A7 (2012-2018) 3.0L

Direct-Fit Ignition Service Kit for 2012-2018 Audi A7

What it Does: Restores factory ignition energy and eliminates high-RPM misfires by replacing degraded coil-on-plug packs and worn spark plugs across all six cylinders.

The Stock A7 Thermal Degradation & High-Boost Spark Blowout

The supercharged EA837 3.0T V6 generates intense engine bay heat soak within the Type 4G8 chassis. Over time, factory ignition coils suffer internal copper winding breakdown and dielectric insulation fatigue from severe thermal cycling. Compounding this, worn plug electrodes increase the required secondary voltage jump, leading to high-load spark blowout, hesitation during boost onset, rough idle, and intermittent misfire fault codes.

The Engineering Solution

This complete ignition kit features six reinforced coil-on-plug assemblies equipped with high-conductivity internal copper windings and thermal-resistant epoxy potting to prevent secondary voltage leakage. Paired with six fine-wire iridium spark plugs, the setup delivers lower arc voltage requirements, superior flame kernel expansion, and high resistance to electrode erosion under supercharged cylinder pressures.
