Tools required:

  • 7/32 socket/ratchet with extension


Step 1: Open the vehicle's hood.

NOTE: We recommend changing ALL ignition coils at the same time, as they often fail in unison. However, during the installation, replace each coil ONE AT A TIME. Also, we'll be disconnecting the sparkplug wires from the coils, and they MUST attach to the same plug when we reattach them!

Step 2: Loosen and remove the 7/32 mounting bolts (2) that secure the ignition coil to the engine.

Step 3: You can now lift and remove the ignition coil.

Step 4: Mount the new ignition coil by tightening the 7/32 mounting bolts (2).

Step 5: Connect the sparkplug wires to the ignition coil. Be sure that they are attached to the SAME PLUG as they originally were!

Step 6: Repeat this process for the remaining ignition coils.
