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

Great product at a great price …. (and) reliability.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Excellent tech help…
My mechanic said that your product was very good, and he was correct.
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.
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
Haven’t used it yet, but we are excited to & Love the way it looks!!
Responsive customer service, kudos to [customer service].
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
