To Gap the Spark Plugs
Flexible Extension for Dual Plug Heads
Care should be taken when installing the top spark plug on S models or any with dual plug heads.
It's easy to get into the wrong position and break the end of the plug with a conventional wrench.
This flexible extension allows you to maneuver the plug into the hole using the handle on the end to start the threads without much force.
If the plug doesn't thread easily, the grip will slip on the plug instead of forcing the threads together and cross-threading them.
Then you simply back it out, re-position and try again until the threads are started correctly.
Once the threads are started, remove the flex tool, use a conventional plug wrench to snug up and then a torque wrench for final tightening.
