Installation Procedure

  1. Install the spark plug wire on the coil.
  2. Install the spark plug wire at each spark plug.
  3. Inspect the wires for proper installation:
    • Push down on each boot in order to inspect the seating.
    • Reinstall any loose boot.
    • Wire routing must be kept intact during service and followed exactly when wires have been disconnected or when replacement of the wires is necessary. Failure to route the wires correctly can lead to radio interference and crossfire of the plugs, or shorting of the leads to the ground.
    • Any time the spark plug wires or boots are installed on the spark plugs, new dielectric grease needs to be applied inside the boot.
