Installation Procedure
- Denso Type SK16R11
- NGK Type IFR5A11
- Replace the spark plugs every 144 000 km (90,000 mi).
- Do not touch the tip of the spark plug.
- Do not damage the iridium surface of the electrode when gapping the plug.
- Do not adjust the gap on used spark plugs. Replace the spark plug if the gap is greater than specification.
- Set the spark plug gap. Bend only the side electrode.
New Spark Plug Gap: 1.0-1.1 mm (0.040-0.043 in)
Maximum Used Spark Plug Gap: 1.2 mm (0.047 in)
- Install the spark plugs to the cylinder head.
Tighten: Tighten the spark plugs to 18 N.m (13 lb ft).
- Install each ignition coil (3) to the cylinder head cover.
- Secure the ignition coils using the bolts (4).
Tighten: Tighten the bolts to 9 N.m (80 lb in).
- Connect each ignition coil electrical connector.
- Install the engine cover (1) to the cylinder head cover. Secure the engine cover with the 2 clips and the 2 nuts.
Tighten: Tighten the nuts to 9 N.m (80 lb in).
IMPORTANT:
Use one of the following types of iridium tipped spark plugs.
IMPORTANT:
NOTE:
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.
