    Spark Plug Inserts

    I have 2 types of the brass inserts for sprk pl. One is a hex head that is screwed in ,the other is just a threaded fitting that is screwd into the head with the plug as the driver. Were these both adaptations or were they a factory fix. Anyone know the pros and cons to using each type? thanks DOUG46CHIEF
