How to Replace the Spark Plugs on a Sail?

[SanMax]

The method for replacing spark plugs on a Sail: 1. Remove the spark plug caps when the engine is cold; 2. Unscrew the old spark plugs counterclockwise; 3. Screw in the new spark plugs clockwise; 4. Reattach the spark plug caps; 5. After all spark plugs have been replaced, check for any errors and start the engine for a test run. If the engine operates normally, the vehicle can be driven as usual. Over time, spark plugs can affect the car's ignition performance and lead to carbon buildup. The voltage provided by the ignition coil is limited, and even with normal use, the wear on the spark plug electrodes increases the voltage required to bridge the spark plug gap. This can result in misfires during rapid acceleration, high speeds, or heavy loads, causing vehicle shaking, difficulty accelerating, and wasted fuel. Therefore, it is necessary to replace the spark plugs regularly to maintain the engine's optimal performance, which also helps in saving fuel.
