What impact does a clogged air filter have on engine sputtering?

A dirty air filter reduces airflow, leading to a rich fuel mixture that can cause engine misfires and sputtering. Discussing how regularly replacing the air filter every 20,000–30,000 km can help improve engine efficiency.

A clogged o r dirty air filter reduces airflow to the engine, which can have the following effects:

Rich Fuel Mixture: When the air filter is clogged, less air enters the engine, which causes a rich fuel mixture more fuel than air. This can cause incomplete combustion, resulting in misfires and sputtering.
Reduced Engine Efficiency: A lack of sufficient airflow reduces the engine’s efficiency, leading to sputtering and poor performance.

Replacing the air filter every 20,000–30,000 km can help maintain proper airflow and prevent sputtering.
