Ignition System: 1H-8
Spark Plug Inspection
S5JB0A1806004
CAUTION
!
• When servicing the iridium / platinum
spark plugs (slender center electrode type
plugs), do not touch the center electrode
to avoid damage to it. The electrode is not
strong enough against mechanical force
as it is slender and its material is not
mechanically tough.
• Do not clean or adjust gap for the iridium /
platinum spark plugs.
Inspect spark plug for:
•Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found for nickel spark plugs, adjust
air gap, clean with spark plug cleaner or replace them
with specified new plugs.
For iridium / platinum spark plugs, replace them with
new plugs.
Spark plug air gap
“a”: 1.0 – 1.1 mm (0.040 – 0.043 in.)
Spark plug type
NGK: BKR6E-11 (Nickel) for M16 and J20 engine
models / IFR6J11 (Iridium) for M16 engine / IFR5J11

models
NOTE
NGK IFR6J11 and IFR5J11 is highly
recommended for better engine starting
performance under –25 °C (–13 °F).
