Ignition Coil and Iridium Spark Plugs for Audi SQ5 (2014-2017) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2014-2017 Audi SQ5

Primary Function: Restores factory ignition energy, stabilizes idle, and eliminates cylinder misfires across the rev range on supercharged 3.0L V6 engines.

The Stock SQ5 Ignition Breakdown Point

The 3.0T EA837 supercharged engine runs under high cylinder pressures and intense thermal cycles within a cramped engine bay. Over time, OEM coil boots degrade from thermal saturation, leading to dielectric breakdown and micro-arcing. Simultaneously, factory spark plug electrodes erode, increasing the plug gap and forcing the coil packs to overwork, which triggers high-rpm misfires, rough cold starts, and persistent ECU diagnostic trouble codes (DTCs).

The Engineering Solution

This complete 6-cylinder ignition kit pairs reinforced coil-on-plug assemblies with high-durability iridium spark plugs. The ignition coils feature premium internal copper windings and heavy-duty silicone boots to resist dielectric leakage under high boost. The fine-wire iridium center electrodes maintain a precise spark gap under continuous thermal load, ensuring consistent flame kernel propagation, complete combustion, and crisp throttle response without ECU calibration issues.
