Overview
Mitsubishi Pajero oil filter plays a key role in maintaining stable engine lubrication.
For this reason, Mitsubishi specifies strict filtration standards for this component.
The filter controls oil flow while capturing contaminants generated during engine operation.
As a result, critical engine parts receive cleaner and more consistent lubrication.
Vehicle Compatibility and Applications
Mitsubishi applies this oil filter across multiple Pajero generations.
Typical vehicles include Mitsubishi Pajero models produced between 2006 and 2021. This OE oil filter is used across Mitsubishi petrol platforms, including Pajero and related crossover derivatives such as Outlander.
Moreover, these vehicles commonly use petrol and diesel powertrains.
Engine displacements usually range from 3.0L to 3.8L for petrol variants.
In addition, selected diesel configurations also use compatible lubrication layouts.
Material and Structural Design
The filter housing uses corrosion-resistant steel material.
Therefore, the exterior maintains strength under oil pressure and thermal cycles.
A precision-machined threaded metal base ensures secure installation.
At the same time, the sealing surface supports stable contact with the engine block.
This structure supports reliable fitment during repeated service intervals.
Filtration Stability and Engine Protection
Engine oil circulation depends on consistent filtration performance.
For this reason, the filter supports stable oil pressure during cold starts.
As a result, wear on bearings and valve train components remains controlled.
Moreover, effective filtration helps extend overall engine service life.
This balance supports predictable performance under off-road and highway conditions.
OE Reference Integration
Mitsubishi assigns OE number 1230A040 to this oil filter.
In addition, interchangeable OE references include 1230A121 for compatible engines.
These OE numbers confirm usage across multiple Pajero engine configurations.
However, vehicle-specific verification remains recommended before installation.
Maintenance and Replacement Guidance
Oil quality degrades due to mileage and operating conditions.
Therefore, technicians replace the oil filter during every scheduled oil change.
Most Mitsubishi service schedules recommend replacement at 10,000 to 15,000 kilometer intervals.
As a result, regular replacement supports long-term engine reliability.
Service intervals should always follow official Mitsubishi maintenance documentation.
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.
