Overview
Isuzu diesel engine oil filter supports stable lubrication in commercial and industrial applications.
For this reason, Isuzu specifies strict filtration and pressure control standards.
The filter manages continuous oil flow while capturing contaminants produced during combustion.
As a result, internal engine components operate under cleaner and more stable lubrication conditions.
Vehicle Compatibility and Applications
Isuzu applies this oil filter across multiple diesel platforms.
Typical applications include Isuzu NPR, NQR, and selected light-duty truck models.
Moreover, the filter supports Isuzu diesel engines used in commercial vehicles and equipment.
Common engine families include 4JG1, 4JB1, and related variants.
In addition, these engines appear in production ranges from the late 1990s onward.
The lubrication layout also supports shared Isuzu industrial engine platforms.
Material and Structural Design
The filter housing uses corrosion-resistant steel material.
Therefore, the exterior maintains strength under high oil pressure and thermal cycles.
A precision-threaded metal base ensures secure mounting during operation.
At the same time, the sealing surface maintains reliable contact with the engine block.
This structure supports consistent fitment across repeated service intervals.
Filtration Stability and Engine Protection
Diesel engines generate higher particulate contamination.
For this reason, the filter supports controlled filtration under extended operation.
As a result, oil pressure remains stable during cold starts and long duty cycles.
Moreover, consistent filtration helps protect crankshaft bearings and valve train components.
This balance supports predictable engine durability in commercial use.
OE Reference Integration
Isuzu assigns OE number 8-94360426-0 to this oil filter.
In addition, interchangeable references include 8-97035862-0 for compatible engines.
These OE numbers confirm application across multiple Isuzu diesel configurations.
However, engine-specific verification remains recommended before installation.
Maintenance and Replacement Guidance
Diesel engine oil degrades with load and operating hours.
Therefore, technicians replace oil filters during every scheduled oil change.
Isuzu service schedules typically recommend replacement every 10,000 to 15,000 kilometers.
As a result, regular replacement supports long-term engine reliability.
Always follow official Isuzu maintenance documentation for service intervals.
Installation and Fitment Notes
This oil filter installs directly onto factory mounting threads.
Moreover, original sealing surfaces remain unchanged during installation.
No modification to surrounding components is required.
Consequently, installation remains straightforward for professional technicians.
