1. Prepare Tools: Gather all necessary tools, including a spark plug wrench, torque wrench, and gap gauge (if required for your application).
2. Remove Old Spark Plugs: Carefully disconnect the ignition coil or spark plug wire from the old spark plug. Use a spark plug wrench to loosen and remove the old spark plug.
3. Compare New & Old: Visually compare the new TORCH spark plug with the old one to ensure they are the correct type and size.
4. Use Spark Plug Sleeve: If applicable, use a spark plug sleeve to protect the ceramic insulator during installation.
5. Install New Spark Plugs: Hand-thread the new spark plug into the cylinder head to avoid cross-threading. Once finger-tight, use a torque wrench to tighten the spark plug to the manufacturer's specified torque. Refer to the torque table below.
6. Install Ignition Coils: Reconnect the ignition coil or spark plug wire to the new spark plug, ensuring a secure connection.

Spark Plug Installation Torque

Remarks: On Diesel Engine Refitted engine or other cast iron engine, the installation torque takes the maximum value of the corresponding value ±3N·m.

Operating Principles and Benefits

Spark plugs are critical components of an internal combustion engine's ignition system. They ignite the air-fuel mixture in the combustion chamber, initiating the power stroke. TORCH Iridium spark plugs offer several benefits:

• Longer Service Life: Iridium's extreme hardness and high melting point resist wear and erosion, extending the plug's lifespan.
• Fast Starts: The fine-wire iridium center electrode requires less voltage to spark, leading to quicker and more reliable engine starts.
• Reduced Emissions: More efficient combustion due to a consistent spark helps reduce harmful exhaust emissions.
• Improved Fuel Efficiency: A strong, stable spark ensures complete combustion, optimizing fuel usage.
• Stable Performance: Consistent spark delivery maintains engine performance over time.

Maintenance

Regular inspection and timely replacement of spark plugs are essential for maintaining engine health and performance.

• Inspection: Periodically inspect spark plugs for signs of wear, fouling, or damage. A healthy spark plug typically has a light tan or grayish-white deposit on the insulator tip.
• Replacement Intervals: Follow your vehicle manufacturer's recommended spark plug replacement intervals. Iridium spark plugs generally have longer replacement intervals compared to conventional plugs.
• Gap Check: While iridium spark plugs are often pre-gapped, it is advisable to verify the gap according to your engine's specifications before installation. Use a wire-type gap gauge to avoid damaging the iridium tip.

Troubleshooting Common Issues

If you experience engine performance issues, spark plugs can sometimes be a contributing factor. Here are common symptoms and potential causes:

• Engine Misfires or Rough Idling: Could indicate a fouled, worn, or incorrectly gapped spark plug.
• Reduced Fuel Economy: Inefficient combustion due to old or damaged spark plugs can lead to increased fuel consumption.
• Difficulty Starting: Weak or inconsistent spark from worn plugs can make starting the engine challenging.
• Loss of Power or Acceleration: Poor ignition can result in reduced engine power output.

If these issues persist after checking or replacing spark plugs, consult a qualified mechanic.
