Spark Plug Inspection

2006 Honda Pilot EX, 3.5 YF2, J35A9SECTION Spark Plug Inspection
  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 plugs 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. If the spark plug electrode is dirty or contaminated, clean the electrode with a plug cleaner.
    NOTE:
    • Do not use a wire brush or scrape the iridium electrode since this will damage the electrode.
    • Use a chemical cleaner such as carb spray to clean contamination on the electrode.
    • When using a sand blaster spark plug cleaner, do not clean for more than 20 seconds to avoid damaging the electrode.
  3. Do not adjust the gap (A) of iridium tip plugs; replace the spark plug if the gap is out of specification.

    Electrode Gap 

    Standard (New): 1.0-1.1 mm (0.039-0.043 in.)

  4. Replace the plug at the specified interval or if the center electrode is rounded (A). Use only the listed spark plugs.

  5. Apply a small amount 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).

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
