Air Filters

10,000 gallons of clean air is circulated to your engine with help from your air filter - for every gallon of gas burned. Air filters keep dust, dirt, and other contaminants from accessing your car's environment, particularly the confined spaces of the engine. Air filters prevent the clogging of engine parts, which can ultimately lead to reduced engine power. Irrespective of how often you clean your BMW, it will always be prone to such harsh elements. Over time, air filters become ineffective and will require replacement. Particles and pollutants aren't good for your engine. Your air filter will likely need replacement if there is a noticeable drop in gas mileage. Even without visiting your mechanic, you can also take a look at the filter yourself to see if it looks excessively worn out or dirty. Replacing the filter is an important part of routine maintenance, so make sure it's on your list of things to do. When replacing an air filter, insist on buying one that is original equipment manufactured, as they boast industry strength and durability.
