All current engines need a subsonic flow of air for entry into the compressor section. The variable inlets supply a flow of air at or near the optimal speed into the compressor section.

Which one of these have variable intakes?

F-4, F14, F-15, F16, F-18, F-18E, F-22, F-35
Rafale, Typhoon, Gripen, Tornado, Mirage 2000, Viggen
Mig-21, Mig-23, Mig 25, Su-27 family, Mig-29

Thanks in advance.
The F-4, F-14, F-18A-G, F-22, F-35, Rafale, Tornado, Mirages III - 2000, MiG-21 - 29 and Su-27 certainly have variable intakes. I am not sure about the others on your list.
