Genuine BMW Air Filter Element – E9X M3 2008-2009 13727838805

Description

The air filter must clean 8000-9000 gallons of air for each gallon of gasoline burned inside the engine, without restricting the air intake.

Air filter replacement at recommended intervals lets an engine breathe properly while protecting it from costly damage. Air filters should be inspected and replaced as needed at least once a year, more often if the vehicle is driven in heavily polluted or dusty conditions.

Engine Air Filter

An engine air filter is a critical component of a vehicle’s intake system, allowing clean fresh outside air to enter the combustion chamber and prevent dust, dirt, and other contaminants from entering the engine. Your engine’s air filter sits within the air intake box and traps particles as air flows into the engine. This ensures that only clean air reaches the combustion chamber, which provides optimal engine performance and fuel efficiency and reduces emissions.

Engine Air Filter Failure Symptoms

• Clogging: Over time, your air filter can become clogged with dirt, dust, and debris, reducing the amount of fresh air that reaches the engine. This can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
• Moisture Contamination: Exposure to excessive moisture, whether from driving in heavy rain or through water, can cause the air filter to become saturated. A wet filter can restrict airflow, further deteriorate over time, and lead to potential engine damage.
• Age: Over time, the materials in the air filter can degrade, losing their ability to filter out contaminants effectively. An old air filter may become brittle and prone to tearing. It is recommended to inspect your engine air filter every 15 – 30,000 miles
• Decreased Fuel Efficiency: When the air filter is blocked, the engine struggles to get the proper air-fuel mixture, causing it to burn more fuel to compensate, resulting in reduced fuel efficiency and reduced performance
• Misfire: Inadequate airflow can lead to incomplete combustion, causing the engine to misfire, which might cause hesitation or weak power build-up under load.
