BMW 320i Air Filters

Your BMW 320i came from the factory with two air filters in place. The first protects your engine, while the second serves your cabin and the HVAC system that cools and heats the passenger space. They work much like the fuel filter and the oil filter do, in that they keep contaminants out of essential systems.

How Air Filters Work

The engine air filter is located near the air intake, capturing pollutants before they can find their way into the engine parts. Without it, those contaminants would quickly build up in your engine and cause problems.

Your cabin air filter can be found under the front cowling of your vehicle. It prevents allergens and irritants from exiting the air vents and getting into the air you breathe.

How to Spot Faulty Air Filters

Over time, however, your air filters will either get too congested with debris or degraded with age to work efficiently. Signs of trouble include:

• Worsening engine performance
• Misfiring engine
• You hear odd noises coming from the engine
• Yur passenger space smells musty
• You can't maintain a consistent cabin temperature
• You hear a whistling sound coming from your air vents
