Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 2015-2020 Audi A3
What it Does: Restores factory ignition energy and combustion stability by replacing degraded coil packs and worn spark plugs with high-dielectric coil-on-plug units and fine-wire iridium plugs.
The Stock A3 Ignition Breakdown
The EA888 Gen 3 engine operates under high cylinder pressures and elevated thermal loads due to direct injection and turbocharging. Over time, factory ignition coils suffer internal dielectric insulation breakdown and secondary winding resistance drift caused by prolonged engine bay heat soak. Simultaneously, factory spark plug gaps erode, increasing secondary voltage demand. This combination manifests as high-load misfires, rough idle harmonics, ignition timing pull by the ECU, and intermittent P0300-P0304 diagnostic trouble codes under boost.
The Engineering Solution
This ignition kit supplies four matched coil-on-plug assemblies engineered with high-conductivity copper primary and secondary windings potted in high-grade epoxy resin to resist thermal degradation and internal voltage arcing. The integrated silicone boots seal out moisture and oil vapor, preventing spark scatter. Paired with four fine-wire iridium-tipped spark plugs, the kit minimizes quench area and lowers ignition voltage requirements, ensuring rapid flame-front propagation, stable cold starts, and consistent spark delivery across the entire RPM band.
