When to Replace Spark Plugs: Signs and Replacement Schedule

Anh Tuan, the owner of a Hyundai H100 truck used for deliveries in Hanoi’s Nguyen Trai Street, once shared a harrowing experience. One day, while transporting a full load of fruit from Long Bien Market to a customer in Ha Dong, his truck suddenly sputtered, violently shook, and stalled on Le Van Luong Street, causing quite a commotion. Panicked, he called for roadside assistance. The mechanic’s inspection revealed the culprit: worn-out spark plugs that were no longer igniting. Since then, Anh Tuan has learned to “treat his truck like his own body,” diligently inspecting and replacing spark plugs regularly.

Anh Tuan’s story serves as a reminder that spark plugs, though small, play a vital role. So, when exactly should you replace your car’s spark plugs? This article provides detailed information on the signs of worn spark plugs and the recommended replacement schedule for different vehicle types.

Spark Plugs: The “Fire” that Ignites Your Engine

Spark plugs are crucial components of a car’s ignition system. They generate the electrical spark needed to ignite the fuel-air mixture in the combustion chamber, powering the engine.

Signs Your Spark Plugs Need Replacing

Spark plugs generally have a long lifespan. However, without regular inspection and replacement, they can wear down and affect engine performance. Here are some signs indicating your spark plugs need replacing:

• Difficulty starting, especially in the morning: Weak spark plugs struggle to generate a strong enough spark to ignite the fuel when the engine is cold.
• Engine misfires, rough idling, poor acceleration: Worn spark plugs hinder efficient fuel combustion, leading to unstable engine performance.
• Increased fuel consumption: Weak spark plugs force the engine to work harder to produce the same power, resulting in higher fuel consumption.
• Wet, black, or fuel-smelling spark plugs: These indicate ignition problems or issues with the fuel system.

Spark Plug Replacement Schedule

Spark plug lifespan depends on various factors, including the type of spark plug, operating conditions, and fuel quality. However, you can refer to the following general replacement schedule:

• Standard Spark Plugs: Replace every 20,000 – 30,000 km.
• Platinum Spark Plugs: Replace every 60,000 – 100,000 km.
• Iridium Spark Plugs: Replace every 100,000 – 160,000 km.

Note: This schedule is for general guidance. Consult your vehicle’s owner’s manual or a reputable mechanic for specific recommendations and regular inspections.
