The BMW 318 Series air filter is a very important little component, helping to keep your engine supplied with the clean supply of air that it needs to produce the power that makes your vehicle function. In order to complete the combustion process efficiently, the engine needs a balanced mixture of air and fuel, precisely calculated to provide a clean burn of the fuel. The air that the engine uses for combustion is forced through the BMW 318 Series air filter before it enters the engine to sift out any impurities it may contain.

Without the BMW 318 Series air filter in place, these particles of dirt and debris could contaminate the interior of the engine, causing abrasive damage and excess wear on the delicate moving parts of the engine. As time passes, the BMW 318 Series air filter will gradually become less efficient, its filtering medium slowly covered by the dirt and debris it has collected.

If not changed in a timely manner, the BMW 318 Series air filter will become clogged, choking off the supply of air that is vital to the efficient performance of the engine. A clogged BMW 318 Series air filter can cause a number of performance problems in your vehicle, such as rough running, hesitation, and poor fuel economy, as well as allowing particles of debris to pass into the engine to cause harm.
