21499613 is supplied as a remanufactured replacement injector. Cross-reference numbers: 21499613, 22340642, 33800-84830, BEBE4G16001. The injector sits at the end of the rail and does the final metering work: it receives fuel already at high pressure and decides both how much enters the cylinder and how well atomised it is. That combination governs power, smoke and fuel consumption more directly than almost any other part on the engine. What owners usually notice first: longer cranking, a rougher idle, more smoke than the engine used to produce, worse consumption, and occasionally a metallic knock that appears under load and clears once the engine is revved. A back-leakage comparison across the set is the cheapest meaningful test: uneven return between cylinders points at the failing unit. Follow it with a cut-out test to confirm which cylinder actually stops contributing. Installation notes: new copper washers and seals are mandatory, the seat must be clean and undamaged, and the retainers should be torqued to the engine manufacturer's specification. If the ECU stores injector codes for this engine, program them after fitting, otherwise the engine will not compensate correctly. Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
