An Engine Monitor is only as good as its probes. That’s why Electronics International (EI) has taken the development of its probes, connectors, and accessories very seriously. EI has been designing and manufacturing probes for over 30 years. All of our probes have been designed in-house by our engineering team. Our team has studied, tested and designed temperature probes since the 1970′s. They have written research documents such as The Pilots Manual – Leaning and Diagnosing Engine Problems and Accurate CHT Measurements.
Just as an Engine Monitor is only as good as its probes, a probe is only as good as its connector. That’s why EI’s engineering team developed EI’s proprietary OLC-1 connector. The OLC-1 connector greatly increases reliability and reduces installation errors as compared to traditional type connectors. Whether you’re looking for a reliable and accurate CHT, EGT, TIT or various other probe types, EI has what you need. With more than a half million probes sold and tested you can count on EI’s reliability.
The E-4 kit includes four (4) P-110F Fast Response EGT Probes.

Awesome Product! Great product and fantastic support!
Sharp-looking gauges. [I chose EI because of your] reputation.
My mechanic said that your product was very good, and he was correct.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
[I chose the CGR-30P because of its] ease of use.
We chose your product because of the great support and reputation your company sustains.
I have never had an issue with any EI products… it looks fantastic on the panel.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
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.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
