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

Convenience is king (or queen) for a busy person
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
I use these plates a lot. Nice looking, nice weight and finish. Good for a quick bite or reheating something in the microwave. Thick enough and heavy enough not to leak. I use 3 different sizes, price is right

Mini paper plates
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
These smaller paper plates are perfect for a quick lunch when you don't need a big plate but just something quick for a sandwich or a dessert. I love these plates because they are so durable. They're sturdy and the value is amazing. I've checked everywhere on pricing and you can't really beat Amazon's prices for these. Additionally, they always arrive on time and they are always packed well. I've been using these for years. I love them. They make my life much easier. (:

Good plates but someone can't count
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
Good plates, exactly what I needed. Sold as 2 packs of 300 but only 1 pack of 300 arrived. Since this is an Amazon deal, they don't give you a way to talk to a seller, only let you make "suggestions" for the future. Only recourse given at that point to to return for a refund. It would appear sending half the order is a common issue with this particular offer.
