Guessing Intake manifold, and if yes and want a cleaner port, can either use the NPP port on the back of the intake if not in use, or if in use for NPP system, then T tap off the NPP line out of it.

There are other ports you can use, but would stay away from them since they are for the PCV system, and let just say a lot of oil vapors being passed through them.
Note, if car is not using the NPP port, still has the wing tab still on the port, once you turn to crack that off, chase the port channel with a small drill bit to make sure that port is open.
