- 100% new: built with no remanufactured components for long-term performance and durability.
- Corrosion-resistant construction: corrosion-resistant brass terminals plus a stainless steel calibration slide and spring resist corrosion for consistent performance.
- Engine-specific metering: laser-drilled metering discs and a high-precision, engine-specific nozzle calibrate fuel flow rates and spray patterns and optimize atomization to help restore engine performance and support fuel economy.
- Optimized sealing: high-temperature Viton® O-rings help seal in extreme conditions to guard against fuel leaks; an O-ring is included.
Each injector is end-of-line tested and calibrated, then validated through lab, climate, and real-world vehicle testing in the USA, so it can be installed with confidence. Quantity varies by application — L6-2.8L engines use 6 injectors and the V8-3.5L uses 8; injectors are sold individually, so order the count your engine requires. Country of origin: Germany.
