Injen Intake Ports

[Galipso]

I have this Injen Intake installed on my car, came with it when i bought it. It's always had these ports on it but nothing connected to them. I only recently found out one of them (Green Arrow) is suppose to connect to my Valve Cover for proper PCV. The other ports, Red Arrow and Orange Arrow, im still not sure what they are for. Also, those 2 black circles are where 3/4" holes are and i have no idea why. Nothing has ever been in them but rubber plugs to seal them and from looking at this pic i now know they are not meant to be there...

The orange has the emissions crap usually under the battery connected to it. The red, I believe, was connected to the factory boost controller. Green like you said, PCV. At least on my 97 GST.

As for the two black, I don't know for sure. Probably aftermarket of some sort.

The emissions I mentioned for the orange typically gets deleted in favor of a cleaner engine bay.

Tunefbysaturnsl is correct, hopefully you've been running the intake with tge ports capped and not open... right?

Yea everything is capped or plugged that is not in use.

That makes better sense, but those two holes still got me wondering. What i should have done is got them welded and closed but i've already powder coated the pipe so i dont wanna melt the powder. Can i just fit 2 discs to size and JB Weld them in from the inside?

I would guess the extra ports may have been added to improve the PCV system. They may have been hooked up to a catch can setup of some sort.

Probably. If anything find out the thread pitch and get a set of plug fittings if you don't use them.

Something like this work?

If you use that I would recommend putting a bead of rtv around it just be sure there are no leaks.
