3/8" NPT RIFE Standard IAT Air Temperature Sensor GM Delphi Connector -10 to 335°F (52-1243)

RIFE Standard IAT / Intake Air Temp Sensors are perfect for use in the range of -10 to 335°F. 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 mean more accurate adjustments to your tune for a safer and more reliable tuneup that you can count on.  

This IAT sensor is our best seller and is typically used for naturally aspirated and intercooled turbo or blower cars, but are acceptable for other application around the vehicle. This sensor is optimized for accuracy and resolution in the 0°-210°F temperature range. 

Features:

  • 3/8" NPT thread
  • 15x Faster Response Time
  • 3x More Accurate Readings
  • Machined and built in house
  • -10 to 335°F
  • Hard Anodized CNC Machined housing

*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.

***The Hi-AT sensor series is typically used for turbo and blower cars as an IAT sensor and for compressor outlet temperature measurement.  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.***

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.

Customer photo review of 3/8" NPT RIFE Standard IAT Air Temperature Sensor GM Connector -10 to 335°F

I dig motion race works, Their products their videos. But...I gotta say, ordering one rife IAT sensor, that Probably wights 2oz and having to pay $30 bucks for shipping, From iowa to Northern arkansas, Well... I felt like the Strawberry sucker that was in the box was mocking me. BUT" If they were to send me a hat to make up for it. ;);) I would pimp the hell out of it 😁

3/8" NPT RIFE Standard IAT Air Temperature Sensor GM Connector -10 to 335°F

I ordered this on 5/25/26, received 5/29/26✓. Realized I ordered the wrong size, and to get ahead of the wait ordered the proper size thinking I'll return the unused one. On 6/3/26, I started the return process and hit the submit tab and was told my items were outside the return window.. So, I looked and my items weren't on sale. So I should've had 30 days, if I read it correctly. So they should been returned less the restock fee, of which I would've asked if a credit could issued as I was planning to buy your LS valve covers with coil pack kit . So the one star is for poor return policy, and I'm out $82. I'm not a whiner, but you asked, so I told you. I got the corrected part and will let you know how you did after the Dyno and tune.
