Filters Filters

Filters from Bosch – the guardians of the engine

For us at Bosch Car Service there is no doubt about it: Quality filters from Bosch protect the most valuable parts of your vehicle. They can be relied upon to keep dirt, abrasion and minute particles out of the injection system, the engine and the passenger compartment. And water too with diesel engines. Which is why our workshops always have the latest range of filters on stock to suit the specific requirements of virtually every make of car and vehicle model.

We recommend: Regular filter replacement

Filters should be checked at regular intervals by an expert and replaced in accordance with vehicle manufacturers' specifications. This is the only way of being sure to avoid loss of engine power and premature contamination of the oil. And to guard the health of driver and passengers, we recommend fitting activated charcoal cabin filters from Bosch. These too should be replaced after every 15,000 km or at least once a year to ensure the reliable filtration of harmful gases, for example.

Diesel filter – indispensable protection for injection systems

The main purpose of a diesel filter is to protect the injection system and engine against particles, water and other residue in the fuel. Durable seal and housing materials, optimum filter media and improved water separation all make diesel filters from Bosch the ideal solution for your car – even when running on biodiesel.

  • Loss of power and even engine stoppage
  • Reduced or interrupted fuel supply
  • Impaired operation of fuel pump and possibly even short circuits
  • Internal corrosion in certain engine components
  • Increased wear

Gasoline filter – effective protection against even the smallest particles

Even minute particles can cause serious wear in the electronic injection system and engine of your car. To ensure optimum operation and a long component service life, Bosch gasoline filters can even remove impurities of less than one thousandth of a millimeter in size from the fuel.

  • Increased wear

Oil filter – to keep your engine running smoothly

An oil filter is necessary to protect the engine against impurities in the engine oil. Short journeys and stop-and-go traffic are a particular source of stress. Frequent cold starting produces more condensate and excess fuel in the mixture. Consequence: Unburnt hydrocarbons and condensate ingress into the oil. These evaporate at high engine temperatures, thus further detracting from the lubrication properties of the oil. To ensure you do not have to think about such things between the recommended maintenance intervals, we advise using top quality oil filters from Bosch.

  • Premature engine wear or even damage
  • Reduced engine power
  • Increased oil consumption
  • Oil leakage

Air filter – end of the line for all sorts of dirt particles

Air is constantly drawn in whilst driving to cool the engine and obtain the correct fuel mixture. The purpose of the air filter is to provide effective protection of the engine against dirt particles and thus premature wear. It also keeps the noise level down. Filter leakage and porosity lead to unmetered air entering the intake duct. And so Bosch air filters feature a particularly hardwearing polyurethane seal which is precisely adapted to the housing shape, offsets any unevenness and remains flexible and supple over the entire filter service life.

  • Poor preparation of the fuel/air mixture
  • Reduced engine power and increased pollutant emissions
  • Higher fuel consumption
  • Increased wear caused by particles
  • Starting problems


Cabin filter – a breath of fresh air

To ensure a pleasant atmosphere at all times when driving, pollen, dust and pollutants first have to be removed from the fresh air being drawn in. Cabin filters from Bosch not only protect your health, but also the air conditioning system in your car. Activated carbon cabin filters provide additional protection against odors and harmful gases. The material used is obtained by the destructive distillation of natural coconut shells with the exclusion of air. The steam required to form the honeycomb structure is heated to a temperature of up to 800 °C. As a result, the internal surface area of 1 gram of activated charcoal is around 1,000 m2 – in other words, one teaspoon full roughly corresponds to the size of a football pitch.

  • Three fiber layers filter the air drawn in
  • Odors and harmful gases are effectively absorbed by the activated charcoal layer
  • Electrostatic charging ensures filtering-out of even the smallest particles which could enter the lungs
  • Reliable operation between -40 and +85 °C
