Ignition Coil and Iridium Spark Plugs for Audi A5 (2010-2014) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2010-2014 Audi A5

Direct Replacement Service Kit: Replaces degrading factory ignition components with high-dielectric coil packs and fine-wire iridium plugs to eliminate misfires and restore combustion efficiency under boost.

The Stock A5 Ignition Breakdown

The EA888 2.0T engine operates under high cylinder pressures and intense thermal cycling within the B8 engine bay. Over time, OEM coil pack internal insulation degrades, resulting in secondary voltage leakage, dielectric boot breakdown, and ignition coil resistance drift. Combined with rapid electrode gap widening on standard plugs from direct-injection combustion heat, the factory ignition system suffers from spark blowout, hesitation under load, rough cold-start idling, and P0300–P0304 misfire diagnostic codes.

The Engineering Solution

This direct-replacement ignition service pack utilizes high-grade internal copper windings to maximize primary-to-secondary voltage transformation and maintain peak dwell stability. High-temperature silicone boots prevent dielectric flashover, while precision direct-fit blade terminal connectors guarantee clean signal delivery from the ECU. Paired with fine-wire iridium spark plugs, this kit provides exceptional fouling resistance, lower ignition voltage requirements, stable flame kernel propagation, and extended service intervals.
