M14 x 1.5 RIFE Hi IAT Air Temperature Sensor Direct Wire 40 to 485°F (52-1249)
RIFE "Hi Temp" IAT / Intake Air Temp Sensors are perfect for 40°-485°F temperature ranges of intake air temps. These sensors feature ultra-fast response thermistors which are not only faster but more accurate than traditional EFI sensors on the market. Fast response times and accurate readings means more accurate adjustments to your tune for a safer and more reliable tuneup that you can count on.
The Hi-AT sensor series is typically only used for turbo and blower cars as an IAT sensor and for compressor outlet temperature measurement. Due to the high temperature ceiling it has, the resolution at lower temperatures will be greatly decreased. They are also acceptable for other applications around the vehicle that require an extended temperature range. The Hi-AT sensor is optimized for accuracy and resolution in the 40°-485°F temperature range.

*Note: Unlike most Motion Raceworks family of products, these sensors like most electronics are not 100% Made in the USA. While we diligently attempt to source all US electronic components, we have not been able to source everything domestically.
Please note: this will not work with Fueltech or Haltech ECU. For these ECU please use part number 52-1248 or Click Here . These standard IAT are able to be configured and run as a "Hi" version from -5 to 450 degrees F.
This sensor will not be a direct plug and play for your factory ECU. You will need to calibrate the ECU to read the sensor data correctly.
