Spark Plug: Service Precautions

CAUTION:
- Spark plug wires must be connected correctly.
- It is important to twist the spark plug wire boots while pulling along the axis of the spark plug to avoid possible damage to the spark plug wires.
- Make sure the spark plug boots are positioned so the spark plug wires do not contact the exhaust manifold.
