Air Filters and Their Impact on Engine Performance

One often-overlooked element of routine maintenance is the engine air filter. A clean air filter is essential for optimal engine performance, fuel efficiency, and longevity.

The Role of the Air Filter

For every gallon of fuel your engine burns, it requires thousands of gallons of air. The air filter's job is to prevent dust, dirt, pollen, and other debris from entering the engine cylinders, where they could cause severe wear and damage.

Symptoms of a Dirty Air Filter

• Reduced Fuel Economy: A clogged filter restricts airflow, causing the engine to run "rich" (too much fuel, not enough air).
• Loss of Power: The engine struggles to breathe, resulting in sluggish acceleration.
• Check Engine Light: An overly rich fuel mixture can trigger emissions-related codes.
• Rough Idling: Restricted airflow can cause the engine to idle erratically.

We recommend checking the air filter at every oil change and replacing it annually or every 12,000-15,000 miles, depending on driving conditions. Stop by Metro Transmission & Auto Repair for a quick inspection.
