SPARK PLUG SERVICE

Recommended spark plug: BPR5ES (NGK)
An incorrect spark plug can cause engine damage.
1. Disconnect the spark plug cap, and remove any dirt from around the
spark plug area.
2. Remove the spark plug with a 13/16-inch spark plug wrench.
3. Inspect the spark plug. Replace it
if the electrodes are worn, or the
insulator is cracked or chipped.
4. Measure the spark plug electrode
gap with a wire-type feeler gauge.
The gap should be 0.028 – 0.031
in (0.70 – 0.80 mm). Correct the
gap, if necessary, by carefully
bending the side electrode.
5. Install the spark plug carefully, by
hand, to avoid cross-threading.
6. After the spark plug seats, tighten
with a 13/16-inch spark plug
wrench to compress the washer.
