factory fuel rails from my 03. not sure of the difference but i believe they flow a little better than non terminator models. only reason for pulling was they wouldnt fit under my new blower. made over 700 on these with e70. comes with Fore fitting to adapt to aftermarket -8 feed lines. missing schrader valve on pass side. i was running an aftermarket fuel pressure sensor that i switched over to the new Fore rails. looking for $50
