0445120134 Common Rail Fuel Injector Replacement

0445120134 is an aftermarket common rail diesel fuel injector intended for matched Cum-mins ISF3.8 fuel-system applications. It is suitable for injector replacement, diesel-engine overhaul and common rail system maintenance when the customer requires a new replacement option instead of an original Bo-sch injector.

The main identifying numbers are 0445120134 and its formatted version 0 445 120 134. Cum-mins number 4947582 is the strongest associated OE reference. Number 5283275 is also frequently used in enquiries and parts-market catalogues, but it should remain a related reference because the same number is sometimes associated with another Bo-sch injector version.

For database construction, the numbers should be separated by function:

Main Product Number: 0445120134
Formatted Number: 0 445 120 134
Cum-mins Reference: 4947582
Related Cum-mins Reference: 5283275
Nozzle Number: 0433172146
Nozzle Type: DLLA141P2146
Control Valve: F00RJ02103

The strongest engine application is Cum-mins ISF3.8. Selected QSF3.8 applications can also be included for discovery because Cum-mins describes 4947582 as an injector used primarily on Euro 5 3.8L ISF/QSF engines. Vehicle references include GAZ Valday and selected Foton Aumark commercial vehicles.

An aftermarket replacement should be inspected for the injector body, electrical connector, high-pressure inlet, return connection, nozzle dimensions and calibration characteristics. Similar external appearance does not prove that two injectors are interchangeable.

0445120304 should not be merged into this product page. Even where 5283275 appears in both product listings, 0445120134 and 0445120304 remain separate Bo-sch injector numbers and should have separate database nodes.

When replacing a complete four-cylinder engine set, injectors of the same manufacturer, quality grade and flow specification should be used wherever possible. Mixing different injector qualities may result in inconsistent fuel correction and uneven engine operation.

FAQ

What replaces 0 445 120 134?

0445120134 and 0 445 120 134 are compact and formatted versions of the same injector number. A replacement must match the OE number and injector configuration.

Is 4947582 the same as 0445120134?

4947582 is commonly used as the Cum-mins reference associated with 0445120134 and ISF3.8 applications.

Is 5283275 the same as 0445120134?

5283275 is related to this injector application family, but it should not be used as the only identification number because it also appears with other injector versions.

Can aftermarket 0445120134 replace the original directly?

Only after confirming the old injector number, connector design, inlet arrangement, engine configuration and calibration requirements.

How many injectors are used on an ISF3.8 engine?

ISF3.8 is a four-cylinder engine, so a complete engine set normally contains four injectors. Final quantity should still be confirmed with the customer.
