Cobra intake install

[withamc]

You'll need to plug the four coolant holes at the corners of the lower manifold. They use an NPT thread, I forget which size. I think that's it - just make sure all your vacuum fittings have a place to go. I used the old vacuum tree off my factory intake.
By the way, can anybody tell me what the vacuum fitting on the front near the throttle body goes to? Right now I've got it plugged.
