Cobra intake question

gray87GT · 02-04-2001, 11:35 PM

Well, while tearing apart my car today I noticed something different. I was comparing my stock intake to the cobra intake and there is a vacuum port? on the side by where the throttle body mounts. On my stock intake I can't find one anywhere. What if anything to I install there? Also, I am sure there are more differences than that I will find when I remove it so can anyone give me some tips on how to do the swap. thanks

The vacuum port near the throttle body goes to the charcoal canister on the passenger side down near the bottom of the radiator. I pulled the vacuum tree off my old manifold and used that for the EGR switch and the FPR. Also don't forget to plug up the four coolant fittings on the corners.
