What's The Diff. Between Ef1,ef2,ef3,ef9

SO WHAT'S THE DIFF BETWEEN THOSE EF CODE STUFF. DO ALL THEIR PARTS LIKE HOOD AND BUMPERS FIT EACH OTHERs?

just incase you dont know. no U.S. 4th gen is an ef

ef series are the jdm versions of the car...ef-9 being the best basically they r like our std dx ex and si

dont forget hf and cx

So, ef9 is the top model than the other ef's rite.

ef describes the body stylin of that car...which would be 4th gen civic/crx's, ef-9's are the si-r's i belive

ED=USDM Civics
EF=JDM Civics

I was gonna do my license plate to where it just said "ED6" but I don't know if that would be wise. People are dumb and may make it into something else.
