Factory BMW Air Filters

Air filters are one of the vital components of a car's engine that are often overlooked but play an essential role in ensuring the longevity and efficiency of the vehicle. Essentially, an air filter is a device that prevents harmful debris, dust, and other particles from getting into the engine's combustion chamber, where fuel is ignited to power the car.

Types of Air Filters

Modern-day cars typically have two types of air filters -- the cabin air filter and the engine air filter. The cabin air filter ensures that the air inside the car's cabin is free from dust, pollen, and other pollutants that can harm a person's health. The engine air filter, on the other hand, protects the engine from contaminants, which can cause damage to the engine's sensitive parts and reduce its lifespan.

How Often to Replace Your Air Filters

A common misconception associated with air filters is that they only need to be replaced when they are visually dirty or clogged. However, this is not always the case. The frequency of replacing air filters depends on several factors, such as the environment in which the car is driven, the quality of air in the region, and the driving habits of the car owner.

What Happens With a Dirty Air Filter

A dirty air filter not only affects a car's performance but can also have an impact on the car's fuel economy. When an engine air filter is congested, it restricts the amount of air that the engine can breathe, resulting in a poorer fuel-to-air ratio. This, in turn, can lead to more fuel consumption and reduce the car's overall fuel efficiency.

In addition to this, a dirty air filter can also lead to increased emissions, posing a risk to the environment. A clogged air filter can cause the engine to run rich, emanating harmful pollutants like carbon monoxide and hydrocarbons into the atmosphere.
