All looks very nice. [I chose E.I. because of] previous experience.

Filip G. from Torslanda, Sweden
Van’s Aircraft RV-6

Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.

Benjamin T. from South Carolina
Piper PA-28-181 Archer II

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

Love the look and having every piece of info in front of me… Better price and look [versus competition].

Gregg J. from Indiana
Piper PA-32R-301T

I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!

Excellent installation instructions [&] recommend[ed] by others.

The R-1-6 is a great instrument. [I chose EI because of] quality.

J. Gregg from North Carolina

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
