1/8' SHORT NPT RIFE High-Performance Liquid Temperature Sensor w/ M5 Connector 52-1225 (Coolant, Water, Oil, Trans Fluid, Fuel)
This sensor is perfect for in-line or cross-flow situations, like in a gauge adapter for transmission fluid, fuel, or oil temperature. Check the picture below for a better idea.
Rife knows how important it is to have an accurate, durable, and fast-acting sensor for your EFI system. A slow-reacting sensor can harm your engine or mess up the tune by giving wrong information based on time and conditions, which stops the ECU from working its safety features or tuning parameters right. While many aftermarket EFI sensors are just re-labeled from 80s and 90s factory tech with slow processing and less importance, RIFE sensors are completely redesigned. They use in-house made bodies and state-of-the-art sensor technology you can rely on!
Features:
- 1/8' NPT threads
- Range: -20F to 300F
- M5 Screw on connector
- Faster response than traditional factory-style sensors in EFI systems
- More accurate than factory-style sensors
- Mating connectors not included
*Note: Unlike most Motion Raceworks family products, these sensors, like most electronics, aren't 100% Made in the USA. We try hard to source all US electronic components, but we can't get everything domestically.
To calibrate your sensor with an aftermarket ECU, refer to the following setup sheets for Holley, Fueltech, and Haltech.

Calibration Info


Using this liquid temperature sensor is easy. First, find a suitable in - line or cross - flow location, like in a gauge adapter for the fluid you want to measure (transmission fluid, fuel, oil, etc.). Then, screw it in using the 1/8' NPT threads. The M5 screw - on connector allows you to connect it to your system. Remember, mating connectors are not included, so you'll need to get those separately. When it comes to calibration, refer to the setup sheets for Holley, Fueltech, or Haltech depending on your aftermarket ECU. Keep in mind that this sensor is very sensitive and accurate. Avoid exposing it to extreme conditions outside its - 20F to 300F range, as it can affect its performance. Also, it's not 100% Made in the USA, but Rife has used the best technology available. For maintenance, just keep it clean and dry. If you notice any issues with the readings, check the connection first. If the problem persists, it might be time to contact support.
