Toyota Alphard / Vellfire Engine Misfire? Spark Plugs Could Be the Cause

If your Toyota Alphard or Vellfire is experiencing engine hesitation, rough idling, or trouble starting — it may be time to replace the spark plugs.

Worn or carbon-fouled spark plugs are a common cause of engine misfires, leading to performance issues, increased fuel consumption, and potential damage to ignition components.

Common Symptoms of Failing Spark Plugs:

• Slow or hesitant acceleration

• Higher fuel consumption

• Engine shaking or rough idle

• Check Engine light illuminated

• Difficulty starting, especially when cold

When Should Spark Plugs Be Replaced?

• Iridium spark plugs: every 80,000 – 100,000 km

• Standard spark plugs: every 20,000 – 30,000 km

Delaying replacement may lead to:

• Misfiring under load

• Ignition coil damage

• Hybrid power transition issues (for hybrid models)

• Catalytic converter strain or failure

Why Choose Toyota Genuine Spark Plugs?

• Designed specifically for Toyota engines

• Longer lifespan (especially Iridium)

• Ensures proper combustion and engine efficiency

• Reduces long-term repair costs
