30+ MPG 2001 GS 430

Can anyone tell me where to locate the Intake Air Temperature Sensor (IAT) or the Coolant Temperature Sensor on the 2001 GS 430? I purchased a module that claims to be able to increase mpg's and hp's.
 
Thanks

Upon searching about IAT I have found this thread. And I just wanna share my opinion.
Not sure exactly, but usually it''''''''s on the air filter box.
However, it could be anywhere from the hole where the air comes from below the filter,
to where the intake hose goes to the throttle body.
