1/4" NPT RIFE Hi IAT Air Temperature Sensor M5 Connector 40 to 485°F (52-1221)

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:

  • 1/4" NPT thread
  • 15x Faster Response Time
  • 3x More Accurate Readings
  • Machined and built in house
  • 40 to 485°F
  • Hard Anodized CNC Machined housing

Good looker but terrible performance
Color: 2-Speed Rechargeable Set with Charging Base
I purchased the product and the base would not attach from the charging module. This is their big selling point. I requested a replacement and sadly the replacement was of the same batch run as the original soo…. Yeah that base would not detach. There are videos showing how easy it is to detach base from charging module. Not theses units. Circle Joy customer service is an @gmail.com. They said base is not designed to be removed frequently. I reminded them the separation feature is their highlighted feature. I was just looking for a base. Circle Joy said no…. If I do not like either unit just return them to Amazon.???? In the meantime, after maybe a dozen grinds, the original unit quit grinding normally and would barely grind at all. I shook it out and it worked again but doesn’t sound right. Two takeaways: 1) Poor product quality. 2) I am sooo done with trying to work with Amazon on replacement items. Save yourself a tone of aggravation and just return the order and reorder if you dare. Otherwise good looking and heavy feel and works great about 10 times. Too bad so sad. Now I have this huge return hassle with Amazon.

Great shakers with convenient dock
Color: Silver, Size: Rechargeable
These are very nice. Work very well. My only complaint is right where I pick them up is the button to turn them in so I’m always accidentally salting the counters lol. Easy to refill. We like the lights. I love that they have a charging dock so they are always fully charged. Very happy with them.

You don’t have to shake it. I love it
Color: Silver, Size: Rechargeable
Different settings from fine to course. It has a light around the bottom where you can see how much you’re using. It stays charged for a while. The quality is great. Well made.
