BMW X7 Air filter replacement
Why does my BMW X7 need the air filter replaced?
The engine in your BMW X7 requires air and fuel to mix and burn inside the combustion chamber, for the engine to run.
Trouble is, the air is extracted from outside of the engine where dirt and debris is floating around. The air needs to be free from contaminants before it enters the engine, so it doesn't cause internal engine damage. That's where the air filter comes in.
This device does exactly what it’s called, it filters the air entering the engine to remove any harmful particles before they can wreak havoc to your BMW X7’s engine.
An air filter replacement can cost between $50 and $200, depending on the type of air filter fitted.
BMW X7 air filters are designed to be changed at regular intervals to prevent the filter from getting clogged up and reduce the airflow into the engine. If the air filter is left dirty and not replaced it can decrease the fuel economy, cause backfiring, rough idling, poor starting and possibly cause the spark plugs to foul up.
If you drive on unsealed roads or often have a lot of contaminants in the air around the vehicle the air filter may need to be replaced more frequently than other BMW X7's.
