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

STA-BIL Start Your Engines! Because Sometimes Engines Need a Pep Talk
Size: 2 fl oz
So, STA-BIL Start Your Engines! is basically that friend who shows up uninvited but actually saves the day. You know, the one who doesn’t ask questions and just gets your engine running when it’s feeling moody or sluggish. Does it work? Of course it does. Like, “put a little in your gas tank, say a quick prayer, and voila!” kind of work. Suddenly your car remembers how to start, and you feel like a mechanic genius without actually lifting a wrench. It’s simple, it’s reliable, and it doesn’t judge you for letting your gas sit around until it gets that “I don’t want to cooperate” attitude. Pros: Makes your engine start like it just had an espresso shot. Easy to use — even if you’re barely awake in the morning. No weird smells or smoke signals, just clean, smooth starting. Cons: Won’t fix your “I forgot to put gas in” problem. Sadly, can’t make your car drive itself to work (yet). You might start relying on it a little too much — hey, no judgment. Final Verdict: ⭐️⭐️⭐️⭐️⭐️ – 5 stars. If your engine is feeling lazy, this stuff just works. It’s like a pep talk in a bottle for your car. Highly recommended for anyone who’s ever cursed their ignition.

Cleans Out Working Carburetors
Size: 2 fl oz
I recommend this product for engines that will in fact start but not run well. I highly recommend it for that specific purpose, which it is designed for. It cleans the inner workings of the carburetor. Of course, you will have a cleaner carburetor if you take it apart and clean it with proper tools and a proper carburetor cleaner. You spray it in the gas tank, start the engine, and let it run a bit. It will not start an engine with a totally plugged up carburetor. Nothing is going to do that. Nor is it a fuel stabilizer, as one previous reviewer seemed to think. Nor is it a product to be used to bring life back to stale gasoline, as another reviewer seemed to think. The only thing to do with stale gasoline is drain it out and pitch it. Nor is it a product to be used for cleaning a carburetor you have taken apart to clean. You should use a proper carburetor cleaner for that purpose. I've given it four stars because it cleans out mildly plugged up carbs. It is not a miracle solution for really neglected carbs as the name suggests.
