I am the tech manager at Autolite spark plugs. You should use some soapy water (a little) around the plug you repaired to make sure it is seated and not leaking. a leaking plug will not properly transfer heat to the cylinder head. this can cause what is called "pre-ignition", a potentially engine damaging runaway combustion event.
