Bosch offers an extensive fuel filter program for nearly all standard vehicle types.

Gasoline filters for carburetor and injection engines
Gasoline conductor filters in carburetor engines protect the valves and so prevent starter problems and poor engine performance.

Filters have become more important due to the growing number of injection engines. Even tiny particles can lead
to severe wear in precision gasoline injection system components. Gasoline filters from Bosch prevent irregular
fuel supply by their sophisticated filter technology and the
filter medium's ideal pore size. Since Bosch develops and produces the entire gasoline injection system, our gasoline filters are tuned perfectly to the injection system's require-
ments. High quality materials guarantee resilience against temperature changes and aggressive fuels.

Fuel filtering alone is not enough for diesel
In addition to filtering out particles, diesel filters also remove water from the fuel. Water is heavier than diesel fuel and collects in the filter's water chamber. After being filtered,
the lighter diesel fuel passes on through the outlet.

Diesel filters from Bosch integrate filtration, water separation, fuel heating and fuel cooling in a single unit. Special filter media ensure a high level of absorption and gently remove
the finest particles. Our diesel filters are guaranteed to remain stable under pressure, even in high pressure injection conditions. Reliable water separation from diesel fuel also contributes to preventing corrosion damage to the engine
and its components.

Regular replacement vital
Perfectly working fuel filters are essential for good engine performance. They ensure that all engine components are protected and therefore help achieve a maximum lifespan for your car, while also reducing fuel consumption.
