The Direction Plus Fuel Manager Post-Filter Kit PF645DPK is designed to protect the engines of late-model common rail diesel vehicles, including Isuzu D-Max, Isuzu MU-X, and Mazda BT-50 models equipped with the 4JJ3TCX 3.0L 4-cylinder diesel engine, produced from 2020 onwards. This kit acts as an additional layer of protection for your engine against particle contamination and the risk of injector failure.

Key features and benefits of installing this post-filter kit on your 4WD include:

• Enhanced Filtration: The kit includes a post-filter that is capable of superior particle removal down to 2 microns. This means it can capture even smaller particles that may not be trapped by the factory-installed fuel filter.
• Clear Water Drainage Bowl: The kit is equipped with a clear water drainage bowl, which makes it easy to identify and remove any water that may have accumulated in the fuel system. Water in the fuel can cause engine issues, and this feature helps keep your engine components clean.
• Prevent Injector Failure: By removing contaminants from the fuel, the post-filter helps prevent the build-up of deposits in the fuel injectors, reducing the risk of costly injector failure.
• Extend Engine Life: Reduced wear and tear on critical engine components, such as the fuel injectors and fuel pump, can help extend the life of your engine, potentially saving you from expensive repairs.
• No Filter Bypass: The kit ensures that contaminated fuel will not be sent to the fuel system even if the filter becomes blocked. This added security helps maintain the integrity of your fuel system.

It's essential to follow the manufacturer's installation instructions and maintenance recommendations for this kit to ensure it provides effective protection for your diesel engine. Regularly inspect and replace the post-filter element as needed to maintain optimal filtration performance.
