To install:

  1. Inspect the condition of the spark plug. Replace if necessary.
    Special care should be used when installing spark plugs in the cylinder head spark plug wells. Be sure the plugs do not drop into the wells, damage to the electrodes can occur.

    Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap. Over tightening can also damage the cylinder head.

  3. Install the spark plug and start threading it by hand. Tighten the spark plugs to 11-15 ft. lbs. (16-20 Nm).
  5. Install the ignition coil to the spark plug. Tighten the mounting bolts to 80 inch lbs. (9 Nm).
  7. Connect the negative battery cable.
