Why do Toyota Camry owners in Pakistan face ignition coil and spark plug failures?

Ignition coil and spark plug failures lead to engine misfires, rough idling, and poor acceleration.
Is this issue linked to Pakistan’s humid climate, dust exposure, and fuel impurities?
What is the recommended spark plug change interval for a Toyota Camry in Pakistan?
Should Camry owners upgrade to iridium spark plugs for better durability?

Causes of Ignition Coil and Spark Plug Failures:

Fuel Impurities: Impurities in Pakistan’s fuel including moisture and dirt can cause carbon buildup on the spark plugs, leading to poor performance, misfires, and eventual failure of both spark plugs and ignition coils.

Humidity and Dust Exposure: Pakistan’s humid climate and dusty conditions can accelerate the wear and tear on ignition coils and spark plugs, particularly if the car is not properly maintained o r regularly cleaned.

Recommended Spark Plug Interval:

The spark plugs should be replaced approximately every 40,000 to 60,000 km, depending on the driving conditions and the type of spark plugs used standard vs. iridium.

Upgrading to Iridium Spark Plugs:

Iridium Spark Plugs are a good upgrade, especially in Pakistan’s harsh environment, as they are more durable, offer better performance, and have a longer lifespan compared to traditional platinum plugs.
