Why Choose Genuine Audi Volkswagen 101905621B?
Genuine Volkswagen Group Component
Reference 101905621B is an original Volkswagen Group spark-plug specification used across compatible Audi and Volkswagen vehicles.
NGK OE Supplier
Catalogue information identifies NGK as the supplier for this Genuine VAG spark plug. The documented NGK cross-reference is PFR6W-TG / NGK 5547.
Correct Engine Ignition
The spark plug provides the ignition spark required to initiate combustion within the applicable petrol engine.
Multiple Audi Applications
Strong catalogue fitment includes selected Audi A4, S4, RS4, A6 / A6 quattro, S6, A8 / A8 quattro, S8, S5 and Q7 applications. Exact application depends on engine specification.
Volkswagen Touareg Application
Reference 101905621B is also documented for selected Volkswagen Touareg V8 applications.
Updated OE Reference
The Genuine Audi catalogue confirms the supersession 101905621A → 101905621B.
Individual Spark Plug
Unless the physical EAT stock package specifically states otherwise, 101905621B should be treated as an individual spark plug, not automatically as a set of 4, 6, 8 or 10. Required quantity depends on the exact engine configuration.
Maintain Reliable Engine Ignition
A worn, damaged or unsuitable spark plug can contribute to symptoms such as engine misfire, difficult starting, rough idle, hesitation during acceleration, reduced engine performance, increased fuel consumption, check-engine warnings and ignition-related fault codes.
These symptoms do not automatically confirm a defective spark plug. Ignition coils, fuel delivery, injectors, wiring, compression and other engine-management components can produce similar symptoms.
Need Help Finding the Right Audi Volkswagen Spark Plug?
Spark-plug selection can vary according to vehicle model, engine displacement, engine code, production month and year, naturally aspirated or turbocharged configuration, existing spark-plug reference and VIN specification.
Provide the complete 17-digit VIN to European Auto Spares for accurate compatibility verification before ordering.
