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.

Features:

  • M14 x 1.5 thread
  • 15x Faster Response Time
  • 3x More Accurate Readings
  • Machined and built in house
  • 40 to 485°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. 

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.

Please note: Thermistors do not have a certain polarity. So when wiring, wire color or pin location on our sensor does not correlate or require specific configuration.

Beloved But Beware Microplastic Chip-Offs
Color: Bacon
My doodle adores this thing and gnaws on it constantly. He has not been able to harm it, which is great. That’s the best part. Things to be aware of: 1. This is mostly molded plastic; it is a bit heavy and very hard. My dog tosses it into the air and if it lands on him, it HURTS. A lot. 2. While it’s sturdy, sharp teeth eventually gnaw pieces and little shavings off the toy. These are microplastics and could be harmful if your dog swallows them.

Very sturdy chew toy
Color: Bacon
My Frenchy loves it! He’s not a large dog, but big for a French Bulldog. (32 lbs). He chews both ends, but prefers the snout. The eyes are cute, but began to peel off within the first week. I easily removed what was peeling. Half of the paint remained intact. When necessary, I will definitely replace it with the same toy.

Great chew toy, long lasting
Color: Bacon
This chew toy has been amazing. We have had it for 2 months with 2 dogs chewy on it and it is still going strong. We have a large Golden who chews on everything and and German Shepherd. Big dogs who chew aggressively. Very impressed! Would definitely buy again!
