Advancements in filter technology are a direct response to changes in engine technology. Modern petrol and diesel fuel systems contain the most accurately engineered components in an engine, manufactured to incredible tolerances of less than two microns and put under enormous loads. Fuel not only burns to make power, but in the case of a Diesel engine, it also lubricates moving parts in the high-pressure fuel pump and injectors. Therefore, the fuel has to be clean. febi’s fuel filters meet the highest requirements: they must be resistant to modern fuels with a high ethanol or bio-diesel content while at the same time they must ensure consistently high flow rates and filter performance over a wide range of temperatures (between -40°C and 100°C). febi offers a comprehensive range of fuel filters in OE matching quality. The best possible filtration performance guarantees optimal engine running at all times. Regular filter changes ensure the performance of the engine. A quality filter must have the capacity and efficiency to reliably protect the engine from contamination between maintenance intervals. Alongside individual components for professional vehicle inspections, febi also offers complete maintenance packages. These contain all of the relevant components, with the exception of fluids. In addition to the fuel filter, these include air, oil, and cabin air filters. The oil drain plug, and all necessary sealing rings, are also included in febi's maintenance packages.
