Great service. [I replaced/upgraded] unit in aircraft.

Adam M. from NSW, Australia
Piper PA-28-181 Cherokee

I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.

Awesome product. Fast easy installation.

Rodney E. from Georgia

I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.

Don K. from Wisconsin

Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.

William F. from Maryland

[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
