Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

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-1 kit includes one (1) P-110F Fast Response EGT Probe.

Very happy with our new tachometer!
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Your products always work great! Great customer service and a quality product that we have used for years.
MVP-50 is a really great product
Easy Install.
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.
Customer Service is far superior… with an excellent record of resolving … technical issues.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Works Great!
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
