How often should the Bisu T5 spark plugs be replaced?
2 Answers
Bisu T5 spark plug replacement interval: 1. The service life of Bisu T5 spark plugs does not exceed 20,000 kilometers. 2. Additionally, you can determine whether to replace them earlier or shorten the manual's "standard" interval based on the symptoms of spark plug failure. 3. When the spark plug shows signs of erosion, such as scarring or damage at the top, or if the electrode appears melted or eroded, it indicates that the spark plug is already damaged and should be replaced immediately. Below is relevant information about spark plugs: 1. Prolonged use of spark plugs can lead to aging, causing an increase in the engine's ignition gap, which results in poor engine performance. 2. If there are issues with the spark plugs, the car may experience difficulties starting, unstable engine idle, engine shaking, poor acceleration, increased fuel consumption, etc. If the engine is not cleaned for a long time, carbon deposits can accumulate, leading to abnormal valve operation and ultimately damaging the engine.
I've encountered many car owners at the repair shop asking about the replacement interval for the Bisu T5 spark plugs. Generally, this vehicle should have them replaced every 40,000 kilometers or so. The exact timing depends on the model year and driving habits—frequent short trips can accelerate spark plug wear, potentially requiring inspection as early as 30,000 kilometers. Spark plugs are responsible for ignition; when worn, they may stick, causing engine misfires, sluggish acceleration, and increased fuel consumption. I recommend having the mechanic check the gap during routine maintenance—don’t wait until the car breaks down. Neglecting this can shorten engine life and even damage the catalytic converter. Safety first: align with the owner’s manual and your driving patterns to develop good habits—it saves money and hassle compared to post-failure repairs.
