Easily replace several of your aircraft’s primary and non-primary engine instruments with one EI CGR For example, simply replace your existing tach with a CGR. In addition to replacing our tachometer, the STC’d CGR will replace MANY of your existing primary and non-primary instruments in the same instrument, in the one 3-1/8” hole. The CGR mounts flush with your panel and doesn’t protrude from your panel (as competitor’s gauges do).
