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.

I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
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!
No specific instrument
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Great service. [I replaced/upgraded] unit in aircraft.
People [at EI] were great to work with.
Your company shares a good reputation!
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Compact, precise, awesome!
