Default ls1 intake rear plug

I am swapping in a standard ls1 intake for height reasons (from the truck intake)

In the rear of the intake there is a plug where the map sensor mounts and a vacuum line for the brakes. This plug seems to be inserted and locked into the rear of the intake.

My problem, or worry, is that i can grab the plug/fitting and rotate it in the intake about 1/8" clockwise/Cclockwise.

So my question is, is this normal? It is not easy to turn, but it does turn. Will this leak?, the motor will be seeing boost too

thanks,

Matt
