Ignition Coil and Iridium Spark Plugs for Audi A5 (2015-2016) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2016 Audi A5

What it Does: Restores factory ignition timing and resolves cylinder misfires across the EA837 direct-injection system with matched coil packs and high-heat iridium plugs.

The Stock A5 Coil Pack Degradation

The forced-induction EA837 3.0L engine generates intense underhood thermal cycles that degrade factory coil-on-plug insulation. Over time, heat-induced micro-fractures in the coil housing cause secondary voltage leakages, high-RPM spark blowout, rough idle, and unburned fuel entering the catalytic converters.

The Engineering Solution

This ignition kit pairs heavy-duty copper-wound coil packs with fine-wire iridium spark plugs to handle high cylinder pressures. The coil packs feature reinforced dielectric housings and corrosion-resistant blade terminals for maximum conductivity. The fine-wire iridium center electrodes resist thermal erosion and fouling, maintaining a sharp spark kernel under peak boost and demanding driving cycles.
