Continental IOX340 series

58 aircraft on the U.S. register carry a Continental IOX340 series engine, rated at about 180 horsepower. The Adam Mayer RANS S-21 is the model most often fitted with it (1 aircraft). The aircraft carrying it were built between 2017 and 2026.

The FAA records engines by code, usually at the level of a series ("O-320 series") rather than the exact variant; this page gathers every FAA code that reads as Continental IOX340 series. FAA spelling: IOX340 SERIES.
