Ignition Coil and Iridium Spark Plugs for Audi RS7 (2015-2018) 4.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2018 Audi RS7

What it Does: The ignition coil and iridium spark plug kit restores factory ignition energy and eliminates high-boost misfires on the 2015-2018 Audi RS7 4.0L twin-turbo V8.

The Stock Audi RS7 Thermal Stress and Ignition Breakdown

The 4.0 TFSI EA824 engine utilizes a "hot-V" configuration, housing twin twin-scroll turbochargers directly inside the cylinder valley. This generates intense radiant heat that saturates the cylinder heads and prematurely degrades factory coil packs. Thermal fatigue breaks down internal winding insulation, weakens the primary/secondary circuit resistance, and compromises the silicone boot seals. Under heavy boost, high cylinder pressures cause spark blowout, micro-arcing, and intermittent misfires that trip the Electronic Power Control (EPC) warning light and trigger ECU safety timing pull.

The Engineering Solution

This comprehensive replacement kit pairs eight high-dielectric pencil ignition coils with fine-wire iridium spark plugs to stabilize secondary spark voltage across the entire rev range. The iridium center electrodes resist high-temperature spark erosion and maintain tight spark gaps under direct-injection cylinder pressures. Heavy-duty boots shield against thermal flashover, preventing voltage leakage into the cylinder head wells. Fully compatible with OEM interchange references UF766, 307134160, and GN10334, this kit installs directly with no harness modifications required.

Frequently Asked Questions

Does this fit the C7.5 RS7?
Yes, this is a direct fit for the 2015-2018 Audi RS7 equipped with the 4.0L TFSI EA824 engine.

Are the iridium spark plugs pre-gapped?
Yes, plugs come pre-set to factory clearance, though verifying gap specification prior to high-boost operation is standard service practice.

The Audi Precision Standard

Preserving clean combustion dynamics is critical for twin-turbo European engines. This kit guarantees clean signal synchronization, eliminating hesitation and preventing unburned fuel from washing cylinder walls or contaminating sensitive downstream catalytic converters.
