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.

USB ports charge.
Relatively cheap, lightweight, and better than most. It gets warm, but not hot. The Video adapter was immediately recognized by my Macbook and works flawlessly at all resolutions made available (much higher than Windows PCs) I used it both as the recipient of my 65W Mac charger, and the Mac received its power from this device; I also had the 65W Mac charger plugged directly into the Mac, and this plugged into the second USB-C plug on the mac. It works (HDMI monitor) both ways. It says that the ports are not for "charging", however be aware that they do charge when devices are connected, for example my iPhone to the extra USB-C port, or the USB-A port. My Logi back-lighted keyboard lights up too. I don't know why they say it is not for charging. Perhaps it is simply saying there are no ports expressly intended to do charging without connecting to your computer.

High quality and all the right connection types
This works great. I've used it for both my MAC and PC. I really love the Ethernet on the end and the HDMI connections (which modern laptops don't include at times). This is a great adaptor and highly recommend.

One complaint
Works very well and solved port issues on my X1 Carbon. My only quibble is that the C interface cable from the unit to the PC is a bit too stiff and tends to lose connection if things move about.

Perfect for my use
Works as intended. Solid build quality and works with my Windows laptop through the USB C connection. I wish the product description would clarify that the USB ports do not support video.
