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.

E.I. Always Exceeds Expectations!
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
The equipment is fantastic, very intuitive, and easy to use.
Good to go! Excellent instructions and easy install. Outstanding instrument!
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.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
The R-1-6 is a great instrument. [I chose EI because of] quality.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
