Help me out here because I am fightting with this. I have the cobra intake. It has three different vacumn ports.mygt8a4re said:my cobra upper has 3 attachment pipes in back. one attaches a vacuum line to the vacuum tree, one that attaches the vacuum line to the fuel regualtor & the one for the pcv line. the pcv line has a bend(elbow shape) while the others are just straight. on mine the lower/middle pipe is for the FPR & the right/drivers side pipe goes to the vacuum tree & as i said before the elbow pipe(left/passengerside) is the PCV.
hope this helps!
