INSTALLATION PROCEDURE
NOTE: If the boot to wire movement has occurred, the boot will give a false visual impression of being fully seated. Ensure that the boots have been
properly assembled by pushing sideways on the installed boots. Failure to properly seat the terminal onto the spark plug will lead to wire core erosion
and result in an engine misfire or crossfire condition, and possible internal damage to the engine.
1. Install the spark plug wires at the distributor.
2. Install the spark plug wire to each spark plug.
IMPORTANT: Wire routings must be kept intact during service and followed exactly when wires have been disconnected or when replacement of
the wires is necessary.
3. Inspect the wires for proper installation:
3.1. Push sideways on each boot in order to inspect the seating.
3.2. Reinstall any loose boot.
