Engine Protection for Harsh Aussie Conditions
Protect your diesel system from costly damage with the Donaldson Diesel Pre-Filter Kit, engineered specifically for Australian right-hand-drive models.
This premium pre-filter system captures water, rust, and fine contaminants before they reach your OEM fuel filter, ensuring clean fuel, longer filter life, and reliable performance whether you’re commuting, towing, or touring off-road.
Modern common-rail diesel engines run at extremely high pressures (up to 3,100 bar / 45,000 psi). Even small amounts of water or dirt can destroy injectors or pumps, repairs that often cost thousands of dollars.
This Donaldson diesel pre-filter kit is designed for Australian right-hand-drive 4JJ3 Isuzu D-Max, MU-X and Mazda BT-50 3.0L turbo diesel models.
The pre-filter captures water, rust and fine contaminants before they reach the OEM fuel filter, helping to protect injectors and fuel pumps and extend OEM filter life.
