The automobile supplier Bosch ensures quality of its automobile parts with its five-step quality assurance system. All products run through the steps development, production, clearance, testing and field observation. Bosch's air filters also run through this five step system. They have a filter medium with synthetic resin impregnation and a sealing lip made of polyurethane. This composite material prevents entering of any particles and foreign bodies into the engine.
Air filters clean the air
Air filters in an automobile have the task of cleaning the air of any foreign bodies before feeding it into the engine. Without air filters, even smallest particles can lead to a high amount of wear in the combustion chambers and the mounts of the engine. For most cars, dry air filters are used, which have a high efficiency because of choice of material, fine pleating and coating. Changing an air filter is necessary after about 50,000 km, depending on the driving style it may be before that as well. Because of the relatively low cost of an air filter in OEM quality, changing it should not be postponed.
Good filters offer a high air flow
Air filters are also responsible for lowering the volume of the engine and damp the suction noise. The challenge for manufacturers like Bosch lies in combining a high efficiency of the air filter with a high air flow. High performance engines need large amounts of air, since the burning process is incomplete and thus inefficient otherwise. Many drivers trust in the long years of experience Bosch can offer.
Changing an air filter is easy
Changing the air filter is easily done even by inexperienced drivers. You will only have to follow the instructions of your car model. Bosch air filters are available from 10 – 20 Euros depending on the model.
