What to Pay Attention to When Installing Spark Plugs?

[McJudah]

Precautions for spark plug installation: 1. Ensure proper alignment of the threads, especially for deep spark plug holes. Use specialized tools, and if significant resistance is felt during threading, avoid applying excessive force blindly to prevent thread damage; 2. When tightening the spark plug, adhere to the specified torque to avoid under or over-tightening, which can lead to gas leaks or damage to the spark plug and its hole; 3. Securely connect the ignition wires to prevent loose connections. Commonly known as spark plugs, their function is to discharge high-voltage pulses from the ignition coil, creating an electric spark that ignites the air-fuel mixture in the cylinder. Main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs.
