You can begin the work of putting in the 2ZR-FE engine control ignition coil and
Spark Plugs by installing 4 spark plugs through use of a 14 mm spark plug wrench with a torque setting of 20 Nm (204 kgf-cm, 15 ft-lbf). The installation of ignition coils requires four bolts where you should torque them to 10 Nm (102 kgf-cm, 7 ft-lbf). Avoid causing damage to the plug cap inside the engine head cover opening and to the upper edge of the spark plug tube when performing this task in the installation process. Complete the procedure by connecting the 4 ignition coil connectors before installing the No. 2 cylinder head cover.
