Check after removal
Under normal operating conditions, use standard spark plugs.
A "hot" spark plug is suitable in cases where carbon deposits form on a standard spark plug under the following operating conditions:
- frequent engine starting;
- low ambient temperature
A "cold" spark plug is suitable in cases where detonation occurs when working with a standard spark plug under the following operating conditions:
- long-distance motorway driving;
- the engine often runs at high speed.
Spark gap (nominal): 1.1 mm
Attention:
- Do not drop or hit the spark plug.
- Do not clean it with a wire brush.
- If there is carbon deposits on the spark plug tip, you can use spark plug cleaner.
- Air pressure in the purifier: Less than 568 kPa (6 kg/cm²)
- Cleaning time: Less than 20 seconds
- There is no need to check or adjust the spark gap between replacements.
Installation
Installation is performed in the reverse order of removal.
