Spark Plug Inspection - L15A1 (IN model) and L15A6
| 1. | Inspect the electrodes and ceramic insulator.
- Burned or worn electrodes may be caused by:
- Advanced ignition timing
- Loose spark plug
- Plug heat range too hot
- Insufficient cooling
- Fouled plug may be caused by:
- Retarded ignition timing
- Oil in combustion chamber
- Incorrect spark plug gap
- Plug heat range too cold
- Excessive idling/low speed running
- Clogged air cleaner element
- Deteriorated ignition coils
 |
| 2. | Check the electrode gap (A). If the gap is over the standard, adjust the gap with suitable gapping tool.
| Electrode Gap | | Standard (New): | 1.0-1.1 mm (0.039-0.043 in.) |
 |
| 3. | Replace the plug at the specified interval, or if the center electrode is rounded (A). Use only the spark plugs as listed.
| Spark Plugs | | L15A1 engine (IN model): | | NGK: | ZFR6K-11 | | DENSO: | KJ20DR-M11 | | L15A6 engine: | | NGK: | ZFR6J-11 | | DENSO: | KJ20CR-M11 |
 |
| 4. | Apply a small quantity of anti-seize compound to the plug threads, and screw the plugs into the cylinder head finger-tight. Then torque them to 18 N·m (1.8 kgf·m, 13 lbf·ft).
