It screws itself backward and forward seating, unseating, screwing just a little bit out, or a lot out. The farther it backs out, the more air it allows to "Go Around" the throttle body plates which in turn increases or decreases rpms. Thays about it, their isn't much to them

Thanks
Makes sense.

Can I PM you some day with more questions?
