cylinder head by hand.
(5) Tighten spark plugs to 28 Nm (20
torque.
(6) Install spark plug insulators over spark plugs. Ensure
the top of the spark plug insulator seals the upper end
of the spark plug tube.
(7) Install ignition coil pack. Connect spark plug cables to coil pack.
The coil pack towers are numbered with the cylinder
identification.
