Keep your Toyota’s engine firing on all cylinders. Spark plugs ignite the air-fuel mixture that powers your vehicle. When they wear out, your engine can lose efficiency, performance, and reliability. At WOW Toyota of Wallingford in Wallingford, CT, we provide professional spark plug replacement using genuine Toyota-approved parts designed for your specific model and engine type.
Why Spark Plug Replacement Matters
Each spark plug delivers thousands of sparks per minute to ignite fuel efficiently. Over time, the electrodes wear down or become coated with carbon, reducing their ability to spark cleanly. This leads to misfires, poor fuel economy, and sluggish acceleration. Replacing your spark plugs at the correct interval keeps your Toyota running smooth and strong.
Signs You May Need New Spark Plugs
- Rough idling or engine misfires
- Decreased fuel economy
- Hard starts or delayed ignition
- Reduced acceleration or power
- Check Engine light illuminated
If you notice these issues, schedule service with our Service Department. Prompt replacement prevents further engine strain and protects ignition coils and sensors from damage.
