Ignition Coil and Iridium Spark Plugs for Audi S4 (2010-2016) 3.0L

High-Dielectric Ignition Coil and Iridium Spark Plug Kit for 2010-2016 Audi S4

Direct-fit primary ignition tune-up kit: Engineered to restore factory secondary voltage, eliminate high-rpm spark blowout, and resolve cylinder misfires across the supercharged 3.0L V6 platform.

The Stock S4 Thermal Degradation

The forced-induction EA837 V6 generates sustained thermal loads within the tight engine bay, causing factory coil pack epoxy potting and silicone boots to degrade over heat cycles. This thermal stress degrades internal primary and secondary insulation, yielding high internal resistance, arcing, and intermittent misfires under high-boost conditions that trigger stubborn EPC warnings and rough idle.

The Engineering Solution

This replacement pack features heavy-duty coil-on-plug assemblies built with high-purity internal copper windings, durable thermoplastic housings, and reinforced dielectric boots to prevent flashover under full cylinder pressure. Paired with fine-wire iridium spark plugs optimized for high-temperature durability, this matched ignition set delivers consistent arc energy, uniform flame front propagation, and rapid throttle response.
