It is a scam!!!!! I know a guy who put one of those in his Intrepid, and went from 24 MPG to 15 MPG. All it does is trick the IAT sensor with a resistor. They also make the car really hard to start. If you order that, I can guarantee you will be very unhappy with it, and you have to hack up your MAF wiring to install it.
