I installed this instrument for a client. I always enjoy installing EI instruments. This was no exception. Great product & company.

Installed in my 182Q. You wont regret it. Having instant digital carb temp readings will give you an entirely different outlook and understanding on whats going on in there and avoiding carb ice. Ice light works great and the reading and light are easily seen during the day. Easy install. I considered keeping the factory indicator but so glad I bought this.

Units works well and installation was straight forward. I only give this 4 stars as the probe wires were mismarked with the wrong probe association. Took a couple extra hours to pull the wires and switch them to the correctly associate probes.
