The fuel filter aims to protect the injection system and the engine against particles, water and other residues in the fuel. Demands on modern vehicles mean diesel fuel filters are required to remove particles smaller than 5 or even 2 microns depending on the vehicle manufacturer, and so the need for precise technology becomes evident.
Bosch offers approximately 95% market coverage, without sacrificing product quality over quantity. All functional and quality tests are performed to the same standards as OE parts, and every fuel filter is subject to a leak test performed with helium in a vacuum chamber.
They don’t stop at high-quality materials and processes but also include optimised alignment of the filter specifications. These specifications influence one another and they must be exactly aligned in order to ensure outstanding filter performance.
The Bosch commitment to quality is evident in their 13 consecutive wins of Best Filter Brand, as voted for by readers of German automobile magazine “auto, motor und sport”.
Fuel needs to be sufficiently filtered to prevent causing major issues with the fuel system down the line. Therefore, it’s important for the fuel filter to be changed regularly to ensure the engine can perform to its best ability. While this tends to be between 30,000 and 40,000 miles, you should refer to the manufacturer’s specifications.
