Description

Professionally Remanufactured & Fully Validated

This fuel injector has been professionally remanufactured to restore proper fuel delivery and consistent engine operation.

Each unit is fully disassembled and undergoes multi-stage ultrasonic and chemical cleaning to remove deposits and contaminants from critical internal areas.

Internal components are carefully inspected, and worn elements are replaced with OEM-grade materials where required to restore reliability and function.

After reassembly, every injector is recalibrated and validated through a comprehensive testing process, including high-pressure leak testing, flow rate matching, spray pattern restoration, and electrical response verification.

Final testing under simulated operating conditions is performed to support stable fuel delivery, efficient combustion, and long-term dependability.

Direct Fit & Plug-and-Play

No tuning or modification is required. Designed to match OEM specifications for seamless installation and dependable operation.

Please confirm compatibility using the fitment section above before purchase.
