Bosch Air Filters: Bodyguard for the engine

Bosch oil, fuel and air filters protect the engine and the injection system from particles and water. And cabin filters protect even the most valuable part of the car: they protect driver and occupants by filtering allergens, fine dust and harmful gases from the cabin air.

Air filter design and operation

Example of an air filter with polyurethane frame.

When should I change my filter?

Possible consequences of a silted-up filter:

Loss of engine power.

Increased fuel consumption.

Increased pollutant emissions.


Maintenance advice:

Respect the interval of maintenance prescribed by the vehicle manufacturer and ask for Bosch quality.

Never clean an air filter to increase its lifetime: risk of damaging it.


For tomorrow’s mobility filters will continue being important!

In future, Bosch will continue providing matching filters – no matter which fuels or drive systems will then prevail on the markets. All powertrain systems need clean water, oil or air for battery or engine cooling.
