295050-1520 8-98243863-0 DENSO Injector — OE Cross-Reference Guide for Isuzu 4HK1 / 6HK1 Diesel Systems

When buyers search for a diesel injector, they often do not start with the engine model-they start with the number stamped on the old part. That is why the 295050-1520 8-98243863-0 DENSO injector is best understood as a cross-reference solution for workshops, parts dealers, and fleet maintenance teams working with Isuzu 4HK1 and 6HK1 common rail diesel engines.

 

 

This injector is commonly searched under several related numbers:

DENSO No.: 295050-1520

OE / Reference No.: 8-98243863-0

Compact format: 8982438630

Related reference: 8-98139816-3

For B2B diesel parts purchasing, these numbers are more than labels. They help confirm compatibility before shipment, avoid wrong-order returns, and make communication easier between the buyer, mechanic, and supplier.

 

 

The 295050-1520 / 8-98243863-0 common rail injector is mainly used for Isuzu 4HK1 and 6HK1 diesel engines, which are widely found in trucks, excavators, wheel loaders, and other heavy-duty diesel equipment. In some markets, buyers also search this injector for Hitachi excavator applications using Isuzu diesel power.

 

 

A common rail injector must match the engine's fuel pressure strategy, ECU control logic, connector type, nozzle behavior, and injection quantity requirements. Even when two injectors look similar, a wrong OE number may cause poor combustion, excessive smoke, unstable idle, hard starting, or engine derating.

That is why we recommend confirming:

✅ old injector number
✅ engine model: 4HK1 / 6HK1
✅ machine or vehicle model
✅ connector and body appearance
✅ required quantity per engine set

Q1: Is 295050-1520 the same as 8-98243863-0?
They are commonly used as matching reference numbers for the same injector category. Always confirm with your old injector label before ordering.

Q2: Can this injector fit both 4HK1 and 6HK1 engines?
It is commonly listed for Isuzu 4HK1 and 6HK1 diesel engines, but the final match should be checked by OE number.

Q3: Should I replace one injector or a full set?
For isolated failure, one unit may be replaced. For high-mileage engines, many workshops prefer set replacement for better fuel balance.

Q4: What symptoms may indicate injector failure?
Hard starting, rough idle, black smoke, high fuel consumption, fuel knock, or weak engine power.

Q5: Do I need to clean the fuel system before installation?
Yes. A contaminated rail, tank, or fuel line can quickly damage a new common rail injector.

Q6: What should I send before purchase?
Send the injector number, engine model, machine model, and clear photos of the old injector.
