Bosch Air Filter 502820957
It's important to check the condition of your cars air filter at regular intervals; we recommend that your air filter is changed every time your car has an annual or 12,000 mile service. Your cars air filter prevents airborne debris such as dust, leaves and other abrasives finding their way into the engine's cylinders where it can mix with the lubricating oil and form an abrasive compound. This will cause wear to the cylinders, pistons and bearings causing permanent damage. If your air filter is left neglected it will get dirty and blocked preventing your engine from sucking enough air into the combustion chamber, this will potentially cause your car to run rough and lose power due to the air/fuel ratio being too rich. We recommend that you check the filter size and shape of your air filter with the picture and dimensions available to ensure correct fitment.Bosch is a leading global supplier of automotive technology and services, as well as industrial technology, consumer goods, and building technology.
