Ignition Coil and Iridium Spark Plugs for Audi A7 (2021-2022) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2021-2022 Audi A7

Primary Function: Restores factory ignition energy, stabilizes idle, and resolves high-boost misfires across the cylinder bank in turbocharged 2.0L TFSI engines.

The Stock A7 Ignition Degradation

The forced-induction EA888 2.0T engine operates under elevated cylinder pressures and tight thermal packaging. Over time, OEM ignition coils suffer from dielectric breakdown and micro-cracking in the epoxy casing due to extreme thermal cycling. Simultaneously, standard factory spark plugs experience electrode erosion from direct-injection combustion heat, increasing the spark gap. This gap widening forces the coil primary windings to draw excess amperage, resulting in high-load hesitation, rough cold starts, unburned hydrocarbon accumulation, and intermittent diagnostic trouble codes (DTCs) like P0300 through P0304.

The Engineering Solution

This complete 4-cylinder refresh kit pairs high-conductivity coil-on-plug assemblies with fine-wire iridium spark plugs. The ignition coils feature premium-grade internal copper windings and reinforced silicone boots that insulate against thermal breakdown and voltage leakage. Paired with laser-welded iridium center electrodes, the system maintains a stable, high-intensity spark arc across the entire rev range, resisting fouling and ensuring uniform flame propagation under heavy boost.
