Removal & Installation
Before servicing the vehicle, refer to the Precautions section.
Remove the upper part of the air cleaner to access the coil packs.
Detach the electrical connector and spark plug wires from the coil pack.
Remove the mounting screw, then remove the coil pack.
Installation is the reverse of removal. Tighten the mounting screw until just snug. Be sure to connect the correct plug wire to the correct coil terminal. Check the terminal a and b identification stamps on the coil, match that to the a and b identification stamps on the cylinder head between the spark plugs.
