Spark Plugs
Servicing Your Honda
Inspect the electrodes and center
porcelain for deposits, corrosion, or
carbon fouling. If the corrosion or
deposits are heavy, replace the plug.
Make sure that a 1.0 mm wire-type
feeler gauge cannot be inserted between
the spark plug gap ( ). If the gauge
fits in the gap, replace the plug with a
new one.
Make sure the plug washer is in good
condition.
With the plug washers attached, thread
the spark plugs in by hand to prevent
cross-threading.
Tighten each spark plug:
If the old plug is good:
1/8 turn after it seats.
If installing a new plug, tighten it
twice to prevent loosening:
First, tighten the plug:
NGK: turn after it seats.
DENSO: turn after it seats.
Then loosen the plug.
Next, tighten the plug again:
1/8 turn after it seats.
