## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Did Its job.
  

*by T***R on Reviewed in the United States 🇺🇸 on January 11, 2022*

Allowed me to use my factory coolant temp gauge for my LS swap in my 88 firebird. Feels a little fragile so i just tightened with caution.

### ⭐⭐⭐⭐ 







  
  
    Fit perfect, good quality, decent price
  

*by A***R on Reviewed in the United States 🇺🇸 on April 4, 2019*

Used to run a mechanical gauge on my LS3. Used in the back of the passenger side head. It does run cooler than the electronic temp sensor in the front of the drivers head, not sure if that is due to its length, or the cool water coming in the passenger side of the motor and exiting the drivers side, hence hotter on the drivers head. overall good quality, and exactly what i needed to get my gauge to work. It does stick out quite far and to remove the spark plug i need to remove this from the head.....

### ⭐⭐⭐⭐ 







  
  
    It works
  

*by B***N on Reviewed in the United States 🇺🇸 on February 11, 2021*

Works well, a little bulky and you may have to disconnect a plug wire to screw it in, but it's fine otherwise.
