This used OEM ignition coil wiring harness and conduit (part number 079971821H) is a genuine Audi part, removed from a donor vehicle. It also replaces earlier versions 079971821G and 079971821F. Designed for the left side of the engine bay, this harness routes power to the ignition coils on 4.0L twin-turbo V8 engines (found in S6, S7, S8, RS7, and A8 Quattro models). A failing harness can cause misfires, rough idle, or a check engine light.
