Ignition Coil & Spark Plugs for Audi A3 Quattro S3 (2015-2020) 1.8L 2.0L I4

High-Output Ignition Coil & Spark Plugs for 2015-2020 Audi A3

Direct Replacement Ignition System: Upgrades the factory ignition components to eliminate misfires and ensure consistent spark delivery under high boost conditions.

The Stock EA888 Ignition Shortcomings

The factory ignition coils on the 2015-2020 Audi A3 and S3 are notoriously prone to premature degradation, especially when subjected to increased boost pressures or aggressive ECU tuning. Over time, the internal windings break down due to extreme engine bay heat soak, leading to weak spark propagation. This weakness manifests as rough idling, hesitation under heavy throttle, and dreaded cylinder misfire codes. Furthermore, standard OEM spark plug electrodes wear down rapidly under the intense cylinder pressures of the turbocharged 1.8L and 2.0L powerplants, compromising combustion efficiency and robbing the engine of potential power and fuel economy.

The Engineering Solution

This comprehensive ignition kit resolves factory misfire issues by combining high-output ignition coils with premium high-performance ruthenium spark plugs. The upgraded coils feature enhanced primary and secondary copper windings, insulated with high-dielectric epoxy to withstand extreme thermal cycling and resist voltage leaks. This ensures a significantly stronger, more stable spark output. Paired with the cutting-edge ruthenium spark plugs—which offer superior durability and melting resistance compared to traditional iridium or platinum—this system guarantees optimal ignition timing and complete fuel burn. The resulting synergy provides smoother acceleration, restored throttle response, and robust reliability for both daily driven and performance-tuned EA888 engines.
