Installation Procedure

NOTE: The plug must thread smoothly into the cylinder head and be fully seated. Use a thread chaser if necessary to clean the threads in the cylinder head. Cross-threading or failure to fully seat the spark plug can cause plug overheating, exhaust blow-by gases, or thread damage. Do not overtighten the spark plugs. Over tightening can cause aluminum threads to strip.
  1. Install the spark plug in the engine. Use the appropriate spark plug socket.

    Tighten the spark plug to 18 N.m (13 lb ft.).

  2. Install the ignition coil assemblies and spark plug boot over the spark plug.
  3. Install ignition coil assemblies and tighten the fixing bolts to the specified torque.
