Ignition Coil and Iridium Spark Plugs for Audi A6 (2000-2002) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2000-2002 Audi A6

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces degraded ignition components on the 2000-2002 Audi A6 2.7L to eliminate boost-onset misfires, stabilize idle speed, and ensure complete combustion under high cylinder pressures.

The Stock Audi A6 Thermal Degradation Problem

The twin-turbocharged APB engine shoehorned into the C5 chassis creates an exceptionally hot operating environment. Factory ignition coils suffer from accelerated thermal fatigue, leading to micro-cracking in the secondary winding insulation and internal epoxy potting breakdown. Coupled with standard spark plug electrode erosion, the weakened OEM ignition system cannot generate the required secondary voltage to jump the gap under peak boost conditions. This breakdown triggers classic cylinder misfires (P0300–P0306 DTCs), ignition hesitation under wide-open throttle, unburnt fuel wash, and catalytic converter damage.

The Engineering Solution

This complete ignition refresh kit replaces tired components with heavy-duty direct-fit pencil coils and premium iridium spark plugs. The ignition coils feature premium high-dielectric epoxy and optimized copper core windings to resist heat-soak impedance drift and voltage leakage. Paired with fine-wire 0.6mm laser-welded iridium spark plugs, this kit provides a sharper spark kernel, lower required breakdown voltage, and superior anti-fouling characteristics. The high-temperature silicone boots effectively isolate secondary voltage within the cylinder spark plug wells, suppressing misfires and restoring crisp throttle response. Directly replaces OEM part numbers 058905105, 058907447C, and UF290.
