Garmin engine monitoring system now available for vintage aircraft

By General Aviation News Staff · June 19, 2025 · Leave a Comment

Garmin has revealed the GI 275 engine indication system (EIS) can now interface with and display information for select 7-cylinder engine applications, allowing vintage aircraft owners to better monitor and manage their radial engines.

The GI 275 EIS serves as an all-in-one primary EIS display, providing indications including fuel and electrical data, oil pressure and temperature, cylinder head temperature (CHT) and exhaust gas temperature (EGT) monitoring, and more.

The GI 275 EIS was intentionally designed to take advantage of the common 3.125-inch flight instrument size, reducing installation time and preserving the existing aircraft panel, according to Garmin officials.

The GI 275 EIS for 7-cylinder engines is available now for select aircraft on Garmin’s Approved Model List (AML), including Continental W-670, Wright R-760, Jacobs R-755, and Jacobs R-915 installations on the following aircraft:

  • Cessna 190, 195
  • WACO YMF
  • Beech Model 18A, S18A, 18D, S18D, A18A, SA18A, A18D, SA18D
  • Howard DGA-15J, DGA-15W

More models are expected to be added to this list in the future, Garmin officials said.

Prices start at $5,570.
