Notice: Twist the spark plug boot one-half turn in order to release the boot. Pull on the spark plug boot only. Do not pull on the spark plug wire or the wire could be damaged.

Caution: Wash your hands after handling coated spark plugs and before smoking. The coating is a non-hazardous material and incidental contact will not cause any adverse effects. However, exposure to polymer vapors - the result of contamination of cigarette products and subsequent burning of the polymer - may result in flu-like symptoms and should be avoided.

Important: Do not remove spark plugs when the engine is warm. Clean dirt and debris from the spark plug recess area.

Tighten
Tighten the spark plug to 15 N·m (11 lb ft).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
