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.Insufficientcooling
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
Worn or deformedelectrodes
Do not adjust the gap of iridium tip plugs (A);
replace the spark plug if the gap is out of
specification.
Electrode Gap:
Standard (New): 1.0 1.1 mm
{0.039-0.0€ in.)
Service Limit: 1.3 mm {0.051 in.l
f .lmproper gap

3. Replace the plug at the specified interval, or if the
center electrode is rounded {A). Use onlV the spark
plugs listed below.
Spark Plugs: lZFR6Kl1 (NGK)
SKJ2ODR-M11 (DENSO)
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, 13lbf ft).
