SPARK PLUG
Recommended Spark Plugs: ZGR5A (NGK)
J16CR-U (DENSO)
The recommended spark plugs have the correct heat range for
normal engine operating temperatures.
Incorrect spark plugs can cause engine damage.
If the engine has been running, let it cool before servicing the
spark plugs.
For good performance, the spark plugs must be properly gapped
and free of deposits.
1. Disconnect the spark plug caps, and remove any dirt from
around the spark plug area.
2. Remove the spark plugs with a 13/16-inch spark plug wrench.

3. Inspect the spark plugs. Replace
them if damaged, badly fouled,
if the sealing washer is in poor
condition, or if the electrode is
worn.
4. Measure the spark plug
electrode gaps with a wire-type
feeler gauge. Correct the gap, if
necessary, by carefully bending
the side electrode.
The gap should be:
0.7 0.8 mm −
5. Install the spark plugs carefully,
by hand, to avoid cross-
threading.
6. After each spark plug is seated, tighten with a 13/16-inch spark
plug wrench to compress the sealing washer.
When installing a new spark plug, tighten 1/2 turn after each
spark plug seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8 1/4 turn
after each spark plug seats to compress the washer.
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
7. Attach the spark plug caps to the spark plugs.
