CHANGING THE FACTORY SPARK
PLUGS
1. Remove the coil covers by gently pulling up on
them. Remove the oil cap prior to removing the
RH coil cover.
2. Disconnect the electrical connectors for each
ignition coil (eight [8] places).
3. Remove the eight (8) fasteners holding the coil on
plug assemblies in place (8 mm socket). Save the
fasteners for re-use.
4. Remove the coil on plug assemblies and label
them so they can be reinstalled in their original
position. A slight twisting motion will break the
seal and ease removal.
5. Use a 5/8" spark plug socket and 6" extension to
remove the eight (8) factory spark plugs and set
aside. These will not be re-used.
NOTE: Use a universal swivel socket at the rear RH plug.
