CAUTION: It is important that technicians wash their hands after handling coated spark plugs and before smoking. The coating itself is a non-hazardous material and incidental contact will not cause any adverse effects. However, exposure to polymer vapors - the result of contamination of tobacco products and the subsequent burning of the polymer may result in flu-like symptoms and should be avoided.
IMPORTANT: Do not remove spark plugs when engine is warm. Clean dirt and debris from spark plug recess area.
1. Make sure ignition key is "OFF."
2. Spark plug wires from plugs.
- Note wire position of wires before removing.
- Twist the boot 1/2 turn while removing.
3. Spark plugs from engine.
