Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Great product at a great price …. (and) reliability.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Great customer service!
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
