The Bosch injector 445110275 is designed for the Common Rail system and directly affects combustion quality, cold-start behavior and engine running. Deviations in injection pressure, injection quantity or spray pattern in suitable HYUNDAI/KIA applications often lead to noticeable rough running.
1) Component identification and catalogue/cross-references
The injector with reference 445110275 is a Bosch Common Rail injector and is supplied as remanufactured. The functional core is the high-precision fuel metering into the combustion chamber; even small deviations in pressure, injection quantity or spray pattern can push the engine noticeably out of its target range.
For unambiguous matching in the parts cross-check, the comparison/catalog numbers are used: 0 445 110 274 and BOSCH 0 445 110 275. In practice, part number 445110275 is matched together with the vehicle data and the details of the old part, because the housing shape, connection and injector variant can vary depending on the engine version.
2) Vehicle compatibility (HYUNDAI/KIA 2.5 CRDi)
Matching is done via TecDoc compatibility data; the following engine families are listed as suitable applications. For ordering, the match of reference number, engine code letters and old-part markings remains decisive.
| Manufacturer | Model/Platform | Engine | Model years (per fitment) |
|---|---|---|---|
| HYUNDAI | H-1 Cargo (TQ) | 2.5 CRDi | 01/2009+ |
| HYUNDAI | H-1 Cargo (TQ) | 2.5 CRDi | 02/2008+ |
| HYUNDAI | H-1 Cargo (TQ) | 2.5 CRDi | 08/2009+ |
| HYUNDAI | H-1 Travel (TQ) | 2.5 CRDi | 05/2008+ |
| HYUNDAI | H-1 Travel (TQ) | 2.5 CRDi | 07/2008+ |
| HYUNDAI | H-1 Travel (TQ) | 2.5 CRDi | 07/2010+ |
| HYUNDAI | H-1 Travel (TQ) | 2.5 CRDi | 08/2011+ |
| KIA | SORENTO I (JC) | 2.5 CRDi | 05/2006-12/2011 |
| KIA | SORENTO I (JC) | 2.5 CRDi | 12/2006-12/2011 |
3) Fitment checks and installation notes
Before installing the Bosch injector 445110275, the old part must be matched to the reference number. The match includes reference number, OEM numbers (if available), engine code letters and vehicle data, because TecDoc compatibility only works reliably when the engine variant matches exactly.
When selecting, the cross-reference logic is relevant: 0 445 110 274 and BOSCH 0 445 110 275 are listed as corresponding comparison numbers. These numbers are used in the parts process to distinguish variants within the same Common Rail injector family; a wrong injector can lead to an unsuitable spray pattern and thus further worsen engine running.
On the installation side, correct fuel metering is the focus: the injector performs the high-precision injection of fuel into the combustion chamber. If after the swap there is still rough engine running or noticeable cold-start behavior, the cause is often not only the injector, but also deviations in system pressure or other components of the Common Rail metering system—therefore matching reference number 445110275 with the old-part details remains the first step.
4) Typical symptoms and selection notes
An injector with an incorrect or worn spray pattern directly affects combustion quality. In practice, this often shows up as rough engine running, problems during cold start, as well as deviations in fuel consumption and power delivery—exactly these functional areas are described for the injector’s operation in the Common Rail system.
The selection should not rely only on the HYUNDAI H-1 Cargo (TQ) or HYUNDAI H-1 Travel (TQ) model, but on the specific reference number 445110275 and the matching engine version 2.5 CRDi. Especially within the production date windows (e.g. 01/2009+ or 08/2011+), injector variants can occur; therefore engine code letters and old-part markings are mandatory points in the match.
If, during the parts process, the comparison numbers 0 445 110 274 or BOSCH 0 445 110 275 appear, the decision should always be made based on the match of reference number 445110275 and the associated vehicle data. This prevents installing an injector with a different design, which can then show up as deviations in pressure/quantity or spray pattern.
5) Suitable Bosch diesel injector 445110275 in the shop context
For the direct part number cross-check, the Bosch diesel injector Common Rail with part number 445110275 is linked: Bosch diesel injector Common Rail 445110275. There, TecDoc matching is supported via the vehicle widget, so that reference number, engine code letters and old-part details can be checked cleanly before placing the order.
Frequently Asked Questions
Which symptoms indicate a defective Common Rail injector?
Typical signs are rough engine running, noticeable cold-start behavior, and deviations in fuel consumption and power delivery. Since the injector performs the fuel metering into the combustion chamber, deviations in pressure, quantity or spray pattern directly affect combustion quality.
How do I know whether injector 445110275 really fits my 2.5 CRDi?
The decisive factor is matching reference number 445110275 with the details on the old part. engine code letters and vehicle data must be checked using the TecDoc compatibility data, because variants can occur within the 2.5 CRDi production date windows.
What role do the comparison numbers 0 445 110 274 and BOSCH 0 445 110 275 play?
These numbers serve as cross-references in the catalogue process for distinguishing variants. Even if they appear in the fitment, the safe decision remains based on reference number 445110275 and the correct vehicle/engine context.
Can a remanufactured Bosch injector 445110275 stabilize engine running again?
The function is aimed at precise fuel metering in the Common Rail system. If the cause is in the injector, returning to a clean spray pattern and correct injection quantity can improve engine running, combustion quality and cold-start behavior.
What should be checked before replacing an injector in the Common Rail system?
Before replacement, reference number, OEM numbers (if available), engine code letters and vehicle data should be matched to the old part. If symptoms persist after the swap, the entire Common Rail metering system must also be checked, because deviations in pressure or quantity can have other causes as well.
