You folks do a great job. Keep up the good work.

Kevin D. from Missouri
Cessna 172 Skyhawk

Great Product, that provides a lot of very helpful engine data in an easy to use and see display!  We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive.  The CGR-30 had quite a few positive reviews online from other users.

Ryan O. from North Dakota
Cessna 182D

Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.

Jason Y. from Arizona

I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
