What are the steps to replace the spark plugs in a Tiida?

The steps to replace the spark plugs in a Tiida are: 1. When removing the high-voltage wire connector, do so gently and avoid forcefully shaking the spark plug insulator, as this may damage the spark plug's sealing performance; 2. Only remove the spark plugs after the engine has cooled down. After loosening the spark plug to be removed, use a thin, soft tube to blow away any dirt around the spark plug to prevent debris from falling into the combustion chamber when the spark plug is removed; 3. The area around the screw, the spark plug electrodes, and the sealing gasket must be kept clean, dry, and free of oil stains, otherwise it may cause issues such as electrical leakage, gas leakage, or weakened sparks; 4. During installation, first align the spark plug with the threaded hole using a socket wrench, then gently screw it in by hand until about half of the thread length is engaged, and then tighten it further with a torque lever; 5. Tighten to the specified torque. If it's too loose, it may cause gas leakage, and if it's too tight, the sealing gasket may lose its elasticity.
