  5. Disconnect the electrical connector from each ignition coil.
  6.  
  7. Remove the bolt securing each ignition coil from the cylinder head cover and remove each ignition coil from the cylinder head cover.
    NOTE
    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.

  11. Inspect the spark plugs for electrode wear, carbon deposits and insulator damage.
  12.  

To install:Important: Use one of the following types of iridium tipped spark plugs.



Denso Type SK16R11
 
NGK Type IFR5A11
 

  1. Replace the spark plugs every 90,000 miles (144,000 km).

    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.
     

  2.  
  3. Set the spark plug gap. Bend only the side electrode.
    1. New Spark Plug Gap: 0.040-0.043 inches (1.0-1.1mm)
    2.  
    3. Maximum Used Spark Plug Gap: 0.047 inches (1.2mm)
      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.
