Yes, many owners report:

Rough idling, hesitation, and power s.

Factory-fitted spark plugs may not be well-suited for high-heat, dusty, low-octane environments.

Possible use of copper-core plugs instead of iridium/platinum, which wear faster.

➡️ The OEM plugs may be of average quality and not ideal for Pakistan’s demanding conditions.
