I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Installation went great. The Fuel Flow is dead on.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Good equipment at a good price. I have used your products before and have had great success.
Easy install, good product. [I chose EI because of my] experience with [the] product.
The reviews online were very good. Customer service has been great.
Best sales team.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
