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. 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 of iridium tip plugs (A);
replace the spark plug if the gap is out of
specification.
4. Replace the plug at the specified interval, or if the
center electrode is rounded (A). Use only the spark
plugs listed.
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.
