jeeepguy All 4.0 engines in Wranglers are H.O. since first introduced in the '91 model year. Prior to that, the engine was a 4.2 and did not have the H.O. designation.

H.O. was a designator given by Jeep to denote the difference between a 4.2 engine and a 4.0 engine... nothing more.

GoHack If I recall right, it's the 4.0L, fuel injected, engine that is the HO.

H.o.

4.0 from 92 and up are H.O. From 92 and lower they are just normal 4.0s
