## Spark Plug Replacement 1.3L

### Removal Procedure

Notice: This engine is equipped with an aluminum cylinder head. Allow the engine to cool before removing spark plugs. Removing the spark plugs from an engine at operating temperature may damage the spark plug threads in the cylinder head. Also be sure to clean any dirt or debris from around spark plug holes prior to removing spark plugs.

1. Remove the spark plug wires (1) from the spark plugs.
2. Remove the spark plugs from the cylinder head.
3. Inspect the spark plugs for electrode wear, carbon deposits and insulator damage. Refer to Spark Plug Visual Diagnosis .

### Installation Procedure

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.

1. Use Denso Type K20PR-U11 or NGK type BKR6E-11 spark plugs.
2. Set the spark plug gap to 1.0-1.1 mm (0.039-0.043 in).
3. Install the spark plugs to the cylinder head.

Tighten
Tighten the spark plug to 28 N·m (21 lb ft).
