[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.

Dom M. from Australia
Van’s Aircraft RV-6

Excellent Service. Superb Product.

Steven N. from Colorado
Cessna 182E Skylane

I have seen your products in other aircraft and have seen their reliability.

Juan P. from British Columbia, Canada
Cessna 172M Skyhawk

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

The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

Casey R. from Oklahoma
Cessna 172M

I really enjoy your products [because they are] simple and easy to use and affordable.

Zach J. from Alaska
Piper PA-16 Clipper

Works Great! Love it!

Rick C. From Florida
Cessna 172R

Have had EI instruments in my past plane and current plane and they always performed flawlessly.

Gary M. from California
Cessna 182Q Skylane

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

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

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.

Mike D. From B.C. Canada
Cessna 210B

Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.

Darrell Lea M.
Piper L-21B Super Cub

Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
