Here's how it works:
* Reduced Airflow: A clogged air filter restricts the amount of air that can reach the engine. The engine needs a precise mixture of air and fuel to combust efficiently.
* Lean Air/Fuel Mixture: With less air, the engine's computer may compensate by reducing the amount of fuel injected. This results in a weaker combustion process.
* Reduced Power Output: Weaker combustion means less power is generated. This can lead to slightly sluggish acceleration and a reduction in the car's overall performance, and potentially a lower top speed. The effect is often subtle, and you might only notice it during acceleration or when driving uphill.
* Increased Fuel Consumption: Ironically, a dirty air filter can *increase* fuel consumption because the engine isn't operating at peak efficiency.
It's important to note that the effect is gradual and often minimal unless the filter is extremely dirty. However, regularly replacing your air filter is essential for maintaining optimal engine performance, fuel economy, and overall vehicle longevity.
