Ignition Coil and Iridium Spark Plugs for Audi A5 (2015-2017) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2017 Audi A5

Direct Replacement Ignition Upgrade: Restores factory spark energy, eliminates high-boost misfires, and stabilizes engine idle across the 2.0L turbocharged platform.

The Stock A5 Dielectric Breakdown and Boost Misfires

Factory coil packs on the EA888 2.0L TFSI engine suffer accelerated degradation due to intense cylinder head thermal cycling and sustained turbocharger heat soak. Over time, OEM primary and secondary windings develop internal resistance drift, while factory rubber boots develop micro-fissures. This causes high-voltage spark leakage, erratic flame kernel propagation, EPC warning lights, and severe misfires under peak cylinder pressure.

The Engineering Solution

This ignition service kit matches four reinforced coil-on-plug units with fine-wire iridium spark plugs. The coils utilize high-grade internal copper windings insulated with thermoset epoxy casing to resist heat-induced dielectric failure. Paired with laser-welded iridium center electrodes that reduce required ignition voltage and resist carbon fouling, this set ensures stable arc delivery, optimized fuel atomization, and reliable cold-start ignition.
