I like how the kits ship with everything needed for install and the wire labeling was very helpful.

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-2 connector. The OLC-2 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.

Phone service for ordering was quick and easy. Shipping was quick.
Easy Install.
We have other EI products currently and have always been satisfied.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Your customer service is excellent and your products are top quality!
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
It works very well; easy operation.
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
