BOSCH Cabin Filter (1987435120) Fits: Bmw 5 Series 523I

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. Bosch always has the latest range of filters on in production to suit the specific requirements of virtually every make of car and vehicle model.

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.
