Ignition Coil and Iridium Spark Plugs for Audi Q7 (2017-2019) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2017-2019 Audi Q7

Primary Function: Restores factory ignition energy and combustion efficiency across all six cylinders by replacing thermally degraded coils and worn spark plugs.

The Stock Q7 Ignition Breakdown

Under continuous supercharger boost, the factory ignition components in the 3.0T engine encounter extreme thermal cycling within the cylinder head recesses. Over time, OEM coil epoxy potting degrades, leading to internal insulation breakdown, secondary winding voltage drop, and intermittent high-load misfires (DTC P0300-P0306). Simultaneously, standard electrode wear increases the spark gap, forcing the factory coils to operate at elevated resistance and accelerating premature primary circuit failure.

The Engineering Solution

This comprehensive tune-up kit features six heavy-duty coil-on-plug assemblies engineered with high-conductivity internal copper windings and high-dielectric silicone boots to eliminate voltage leakage under high cylinder pressures. Paired with six fine-wire iridium spark plugs, this setup ensures high thermal conductivity, stable spark kernel formation, and consistent flame propagation without requiring harness modifications or ECM calibration.
