Factory service manual diagram



1. Ignition Off.
2. Remove air induction resonator.

IMPORTANT: Note which spark plug wire is removed from which coil tower. The spark plug wires must be connected to the correct coil towers.

3. Remove two upper EI module bolts.
4. Using a small, flat-bladed screwdriver, remove spark plug wires from the coil tower by gently prying between the FT module and the black connector position assurance (CPA) housing.
5. Disconnect EI module harness connector.
6. Remove two lower EI module bolts.

INSTALLATION

NOTE:
^ Verify threads of bolts, mounting surface and threaded holes are clean and free of any residue.
^ Use care when installing the EI module bolts. Make sure the bolt head is seated on the EI module when the torque specification is reached. If the bolt head is not seated on the ignition module, remove the bolt and tap the hole to clean any debris from the threads.
^ Over torquing of the EI module will result in cracking the coil housing and damaging the coil.
