The Role of Air Filters in Car Performance – When to Replace Them
Your engine needs clean air to function efficiently. Air filters remove dust, dirt, and debris before they reach the combustion chamber. In Kenya, with dusty roads and heavy traffic, car air filters in Kenya play an even more critical role in protecting your engine and boosting performance.
Why Air Filters Matter
Air filters ensure the right air-to-fuel mixture for combustion. A clogged filter reduces airflow, forcing your engine to work harder. This results in poor fuel economy, reduced power, and increased emissions.
Benefits of Clean Air Filters
- Improved Performance: Better airflow means smoother acceleration.
- Fuel Efficiency: Clean filters reduce fuel consumption.
- Longer Engine Life: Prevents dust and particles from damaging engine parts.
- Reduced Emissions: Cleaner combustion helps the environment.
Signs Your Air Filter Needs Replacement
- Reduced acceleration power
- Increased fuel consumption
- Black smoke from the exhaust
- Unusual engine sounds
- Visible dirt on the filter
