BK2Q-9K546-AG is supplied as a remanufactured replacement injector. Cross-reference numbers: BK2Q-9K546-AG. This is the last precision component in the fuel path. Everything upstream exists to deliver clean fuel at stable pressure; this unit decides when combustion starts and how completely the charge burns. That is why injector condition shows up so directly in noise, smoke and emissions. Typical signs are poor starting hot or cold depending on whether the unit is weeping or sticking, an idle that hunts or sounds uneven, smoke under acceleration, and sometimes a smell of diesel in the oil where an injector is leaking internally. Before replacing anything, distinguish injector faults from their look-alikes. Comparing return volume between cylinders and running a cut-out test on a diagnostic tool will show which cylinder is actually contributing — cheap checks that prevent replacing parts that were not faulty. Fit as a matched set rather than singly — one new injector among worn neighbours reproduces the uneven running you set out to cure. New sealing washers every time, clean seats, correct torque, and where applicable, program the injector codes into the ECU once fitted. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
