Customer Testimonials

I have several EI units in my aircraft and have been very pleased with their reliability over the years. The other great part, besides the unit themselves, is the support from you all. Thank you for your support over the years… I chose IE for your reputation for quality and pricing. I have been very pleased with my units. My graphic engine analyzer, fuel flow meter, volt/amp meter, RPM and now Manifold gauge.

Boyd G. from Arizona

Cessna 182J Skylane

M-1 Manifold Pressure Instrument

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!

C Scott Van W. From Idaho

Cessna 175 Skylark

CGR-30 Combo Package

Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.

Dale C. from Ohio

Cessna 182D Skylane

CGR-30P Premium Engine Monitor

I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.

Charles M. from South Dakota

Cessna 150F

R-1 RPM Tachometer Instrument

Big improvement over old cluster (gauges). Good customer service.

William P. from Louisiana

Cessna U206

CGR-30P Premium Engine Monitor

After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.

Ralph M. from Florida

N272TC

CGR-30P Premium Engine Monitor

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.

Brewer P. from Mississippi

Beechcraft Bonanza V35B

VA-1A Volts/Amps Instrument

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

Piper PA-28-150

E-1P Single EGT Primary Instrument

The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
