### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent Temp Gauge for air cooled engine
  

*by D***G on Reviewed in the United States on July 8, 2020*

I really like this temp gauge I installed on John Deere riding lawn mower. I had to splice in longer wires for the spark plug connection but next time I will buy an extension cable because they have four different length cable extensions.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Sensor lead is too short
  

*by A***U on Reviewed in the United States on May 26, 2020*

I got the spark plug mounted temp sensor and the lead is 24 inches long. Trail tech please wish me luck mounting this on a bike LOL
