Match a replacement diesel injector to the complete original part number and exact engine application. Do not choose by vehicle name, engine family or appearance alone. Confirm coding requirements with your installer before purchase.
Compare these four references
| Injector listing | Supplier cross-reference | Application reference in catalog |
|---|---|---|
| 33800-4A700 | 28236381 | KIA |
| 33800-4A710 | 28229873 | KIA |
| A6510701387 | 28230891 | OM651 |
| A6460700987 | EJBR04201D | OM646 |
These rows are separate catalog listings, not confirmed substitutes. The KIA reference does not identify a complete vehicle-and-year fitment list. OM651 and OM646 are different application references; neither establishes fitment for every vehicle carrying that engine-family name.
What to send for a fitment check
- A clear photo of the complete original injector reference, including all letters and suffixes.
- Vehicle make, model and year, plus the engine model and serial number where available.
- The product reference you intend to order and the number of injectors required.
- Connector and installation photos where safely accessible; do not dismantle a fuel system just to obtain a photo.
Part number versus correction code
The product reference identifies the assembly being ordered. A correction or calibration code, where used, relates to configuring the injector for the vehicle. Ask the installer to confirm whether coding is required and which supplied code must be used. Do not assume that matching the part number completes the installation process.
Quantity and accessories
These four listings are priced for one injector assembly, not a full engine set. Check the number required after diagnosis. Confirm seals, fittings and other installation items against the packing list before checkout; a product photo does not prove what is included.
Frequently asked questions
Can I swap 33800-4A700 for 33800-4A710?
This guide does not establish interchangeability. They have different complete references and supplier cross-references. Request a check against your original injector and exact application.
Does an OM651 reference guarantee fitment for my Sprinter?
No. The engine-family and vehicle names are not a substitute for matching the original injector reference.
Should I replace an injector before diagnosis?
Have the fault assessed first. This checklist helps identify a purchase; it does not diagnose a fuel-system fault.
Technical background: Delphi's common rail injector guidance explains checking the correct part number and correction code during replacement. Follow the procedure for your exact application.
Ask for a compatibility check
Contact VANTORIX with the exact product reference and the information listed above. Confirm compatibility and package contents before ordering. Product references below come from our current supplier listings; they are not an independent OEM interchangeability certification.
