What is Spark Plug Gap Tool ?

A specialist tool made especially for adjusting the gap on iridium spark plugs is the Iridium Spark Plug Gap Tool. Iridium spark plugs have a predetermined gap that shouldn’t be changed, compared to conventional spark plugs, which frequently need to be manually gapped using feeler gauges. However, wear or damage may occasionally require changes.

Significance of Proper Spark Plug Gap

The distance between the electrode and the spark plug’s center tip is a crucial factor in ignition efficiency. An improper gap can result in misfires, poor fuel combustion, and diminished engine power. Iridium spark plugs have a delicate design and precision engineering, making gap maintenance even more important.

Steps Of Using Iridium Spark Plug Gap Tool

  • Preparation: Start by ensuring the engine is cool and the ignition is turned off. Remove the spark plug wire from the plug you wish to adjust.
  • Inspection: Carefully examine the spark plug to check for any signs of damage or wear. If the electrode appears worn or bent, replacement may be necessary.
  • Adjustment: Insert the Iridium Spark Plug Gap Tool into the gap between the electrode and the center tip of the spark plug. Gently apply pressure to adjust the gap as needed, taking care not to bend or damage the electrode.
  • Verification: Once the gap is adjusted, double-check it using a feeler gauge to ensure it matches the manufacturer’s specifications. Make any necessary adjustments until the gap is within the recommended range.
  • Installation: Carefully reinstall the spark plug into the engine and reconnect the spark plug wire. Repeat the process for each spark plug that requires adjustment.
