Ignition Coil and Iridium Spark Plugs for Audi Q5 (2010-2015) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2010-2015 Audi Q5

Direct Replacement Ignition Service Kit: Restores factory secondary ignition voltage and combustion efficiency across all four cylinders to eliminate misfires, rough idle, and acceleration hesitation.

The Stock Q5 2.0 TFSI Ignition Coil Thermal Breakdown

The EA888 engine platform subjects coil-on-plug modules to intense turbocharger thermal saturation and high cylinder pressures. Over time, heat cycles degrade factory internal epoxy insulation and primary/secondary copper windings, causing micro-arcing and intermittent dielectric breakdown under boost. Concurrently, standard spark plug electrodes erode, widening gaps, overworking the ignition coils, and triggering P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This comprehensive service pack pairs four heavy-duty coil packs with fine-wire iridium spark plugs for precise spark kernel initiation. Each coil assembly features high-conductivity copper windings, reinforced dielectric housings, and factory-matched blade terminals that withstand continuous high-temperature exposure. The paired iridium plugs offer superior thermal threshold stability and erosion resistance, maintaining tight plug gaps under forced induction loads to guarantee smooth idle, prompt cold starting, and consistent high-RPM performance without triggering Check Engine Lights.
