Spark plug service
Recommended spark plug: BPR5ES (NGK)
W16EPR-U (DENSO)
To ensure proper engine operation, the spark plug must be properly gapped
and free of deposits.
1. Open the rear maintenance cover.
2. Remove the spark plug cap.
3. Clean any dirt from around the spark plug base.
4. Use the plug wrench to remove the spark plug.
5. Visually inspect the spark plug. Discard the spark plug if there is apparent
wear, or if the insulator is cracked or chipped. Clean the sark plug with a
wire brush if it is to be reused.
6. Measure the plug gap with a feeler gauge.
The gap should be 0.7 – 0.8 mm (0.028 – 0.031 in).
Correct as necessary by carefully bending the side electrode.
