OE 078905104 Ignition Coil with Premium Copper Windings and High-Temperature Resistant Insulating Housing for VW Audi

This Ignition Coil with OE number 078905104 is an essential engine system replacement part, compatible with Volkswagen Passat 2.8, Audi A4 and A6 2.4L and 2.8L V6 engines. It converts low voltage from the battery into high voltage to power the spark plug, igniting the fuel-air mixture in the combustion chamber reliably. A faulty ignition coil often triggers engine misfire, rough idle, sluggish acceleration, higher fuel consumption and an illuminated check engine warning light.

Constructed with premium copper windings and high-temperature resistant insulating housing, it delivers stable voltage output, excellent heat resistance and anti-interference performance, adapting to harsh high-temperature conditions inside the engine bay. Manufactured strictly following OE specifications, it ensures precise fitment and simple plug-and-play installation without extra modification. Every coil undergoes strict ignition performance and durability testing before shipment. It is a trusted aftermarket spare part favored by auto repair shops and auto parts distributors.
