IAC Valve, which should I buy?

[Izzmo]

There are some IAC valves on RockAuto for ~79 for the Motorcraft ($101 at Oreilly's.. wtf)

RockAuto also has one for $30 from KEMPARTS.. should I go with that?

Wish I knew, it is pretty tempting. I have never bought one, just cleaned up the existing one.
I know with O2 sensors, I pay the premium for the Motorcraft because I know they actually work well.
I would try it.
That is how I know the other O2 sensors don't work.... it is because I tried them and they failed.

I think Bosch makes pretty good O2 sensors as well. Mine have been working good so far.
