Correct. Make sure u get a 2 way and not a 1 way. I bought a 1 way and they wouldn't let me get a refund when I found out they screwed me. U can also drill a hole in ur stock gas cap if u don't wanna buy a new one. U just pop it apart and drill a hole in one of the pieces (I can't remember which.. bottom part I think) diagonally and ur good to go.
