  3. CAUTION: Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
    NOTE: For flexible fuel (FF) vehicles, if an original spark plug is reused, make sure it is installed in the same cylinder from which it was removed. New spark plugs can be used in any cylinder.
  4. Install the 6 spark plugs.
    • Tighten to 15 Nm (11 lb-ft).
  5. CAUTION: Make sure the spark plug boots are positioned so that the spark plug wires do not contact the exhaust manifold, or any sharp edges.
    NOTE: Apply silicone brake caliper grease and dielectric compound to the inside of the spark plug wire-to-spark plug boots.
  6. Connect the spark plug wires to the spark plugs.
