Meter fuel precisely and keep combustion clean with the Standard Ignition Fuel Injector FJ890, a 100% new, top-feed MFI (multiport) injector that installs as a direct-fit replacement on the 2001-2003 Audi S6 and 2001-2003 Audi S8 (V8-4.2L). Built new from the ground up — no remanufactured components — it is end-of-line tested and calibrated so it can be installed with confidence.
- 100% new construction: made entirely from new parts for long-term performance and durability.
- Engine-specific metering: laser-drilled metering discs calibrate fuel flow rates and spray patterns, while a high-precision nozzle optimizes atomization for efficient combustion — helping restore engine performance and support fuel economy.
- Corrosion resistance: corrosion-resistant brass terminals plus a stainless steel calibration slide and spring provide consistent performance.
- Optimized sealing: high-temperature Viton O-rings help seal in extreme conditions to guard against fuel leaks; includes an O-ring.
It carries two male blade terminals and a gray finish, and was validated and tested in the USA. Rough idle, misfire, hesitation or poor fuel economy can be signs an injector may need replacing — diagnose the cause first, and if a failed injector is at fault, this replaces it. Sold individually; the listed V8-4.2L applications use eight injectors per engine. Country of origin: Germany. Manufacturer part number FJ890.
