Ignition Coil and Iridium Spark Plugs for Audi Q3 (2015-2016) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2015-2016 Audi Q3

What it Does: Restores direct-spark energy delivery across all cylinders to eliminate misfires, rough idle, and combustion instability under boost.

The Stock Q3 Ignition Degradation

The EA888 turbocharged direct-injection engine generates intense cylinder head thermal cycling that degrades factory coil secondary windings and epoxy insulation over time. High internal resistance leads to dielectric breakdown, intermittent spark blowout under boost, unburned hydrocarbon buildup, and recurring P0300-series misfire trouble codes on aging factory assemblies.

The Engineering Solution

This comprehensive tune-up kit pairs heavy-duty coil-on-plug units with premium fine-wire iridium spark plugs. The ignition coils utilize high-grade internal copper windings and high-dielectric epoxy potting to withstand severe heat soak and prevent voltage arching. Precision-welded iridium center electrodes maintain tight spark gaps under direct-injection boost pressures, ensuring complete flame-front propagation, crisp throttle response, and smooth idle stability.
