Are frequent air filter and spark plug replacements required in Changan Karvaan due to Pakistan’s dusty environments?

Dirty intake components can choke the engine and increase fuel consumption. Are owners performing timely replacements based on local driving conditions?

Absolutely. Pakistan’s dusty roads, brick kilns, and smoke mean:

Air filters get dirty every 3,000–5,000 km.

Spark plugs get fouled faster, especially with low-grade petrol.

Not replacing these on time leads to:

Higher fuel consumption

Weaker performance

Engine hesitation and misfire

➡️ Owners should follow a local climate-based maintenance schedule, not just the manual.
