For Pakistani conditions, iridium spark plugs are highly recommended due to:

Longer lifespan 60,000–100,000 km

Better resistance to carbon buildup

Stable performance under rough fuel conditions

However, copper spark plugs are cheaper and used widely in workshops. They need replacement every 20,000–30,000 km, especially if you’re driving in heavy traffic o r dusty environments.

Top brands for Swift in Pakistan:

NGK Japan – Trusted and widely available

Denso Japan – OEM quality

Bosch Germany – Premium iridium/platinum options

Stick to the OEM heat range and always get plugs gapped correctly according to the Swift’s engine specs usually 1.0–1.1 mm for M13A engines.
