Do clogged air filters o r malfunctioning mass air flow sensors MAF in Changan Kalam contribute to increased exhaust emissions in Pakistan?

Mechanics report airflow issues raising emissions. Are these components durable enough for dusty environments?

✅ Yes — very common in dusty environments like Pakistan.

Clogged air filters:

Restrict airflow

Lead to rich mixtures and black smoke

Malfunctioning Mass Air Flow MAF sensors:

Miscalculate fuel-air mix

Cause rough idling, low mileage, and high emissions

These components are cheaply built in many Chinese LCVs and wear out quickly.

🧰 Solution: Clean o r replace filters/sensors every 5,000–8,000 km.
