SPARK PLUG
Using a spark plug of incorrect size or heat range can cause serious
engine damage.
The standard spark plug is:
For cold climate (Below 5 °C, 41 °F):
X22EPR-U9 (DENSO)
X20EPR-U9 (DENSO)
DPR6EA-9 (NGK)
DPR7EA-9 (NGK)
To check and change the spark plug:
Disconnect the spark plug cap.
Clean any dirt from around the spark plug base.
Remove the plug with the wrench provided in the tool kit.
Visually inspect the spark plug electrodes for wear. The center
electrode (Fig.
) should have a flat tip and sharp edges, and
the side electrode ( ) should not be eroded. If the electrodes and
insulator tip appear unusually fouled or burned, we suggest that
you contact your authorized Honda dealer.
Discard the spark plug if there is apparent wear or if the insulator
is cracked or chipped.
Using a wire-type feeler gauge, make sure that the spark plug gap
is correct. If adjustment is necessary, bend the side electrode
carefully.
The gap should be:
0.8
0.9 mm (0.03
0.04 in)
With the plug washer attached, thread the spark plug in by hand to
prevent cross-threading.
After threading by hand, tighten a new spark plug 1/2 turn with the
spark plug wrench to compress the washer. If you are reusing a
plug, it should only take 1/8
1/4 turn after the plug seats.
