ATS Intake Air Temp Sensor Kit includes GM Fast Response Intake Air Temp Sensor, connector pigtail, and mounting plate to install in original cold start injector location on a Gen2.

Compatible with almost all stand alone ECUs (not compatible with Autronic) and Gen3 stock ECUs.

When installing in place of original air temp sensor in the AFM, wire the two wires on the ATS IAT sensor to the brown and black wires originally going to AFM. Sensor works by measuring a change in resistance so polarity does not matter.

Note: If you are still using a stock type fuel rail, be sure to add the cold start block off bolt to avoid a massive fuel leak when removing the CSI.
