Ignition Coil and Iridium Spark Plugs for Audi A5 (2018-2019) 2.0L

Direct-Fit Ignition Service Kit for 2018-2019 Audi A5

What it Does: Restores factory ignition energy and combustion efficiency by replacing degraded coil-on-plug units and worn spark plugs with high-dielectric copper-wound coils and fine-wire iridium plugs.

The Stock A5 Ignition Breakdown

The turbocharged EA888 engine subjects ignition components to intense thermal cycling and high cylinder pressures. Over time, factory coil housings suffer micro-fracturing and dielectric breakdown due to sustained heat soak, leading to internal resistance drift, secondary voltage drop, and spark blowout under boost. Concurrently, factory plugs experience electrode erosion, increasing the gap and forcing deteriorating coils to work harder, resulting in rough idling, cold-start hesitation, and high-load misfires.

The Engineering Solution

This comprehensive tune-up kit features heavy-duty coil-on-plug assemblies engineered with high-purity internal copper windings, durable thermoplastic housings, and reinforced blade terminals for stable high-voltage output. Paired with high-melting-point fine-wire iridium spark plugs, this package ensures lower required firing voltage, superior thermal dissipation, and consistent flame front propagation across the entire RPM band.
