DIY Ultimate Greddy Turbo CAI for AP owners
Return line to the intake after the MAF; the send line from the crank case vent.
The Jet Air Mix from the boosted side (on the last pipe) and OMP on the 2nd nipple on the greddy intake pipe (or vice versa - I can never remember). Then cap the two nipples on the IUM.
That is how my 2007 is wired.

Ok, let me confirm. I am still a bit sketchy where as i can't see exactly where everything goes in the picture. I think I got most of it right, but I want to confirm. Where did the hose originally go to, before it was attached to the oil catch can? I can't seem to follow it far enough, it goes deep down in the engine bay. I'm assuming i unhook that hose and connect a hose from the oil cap to the catch can. Then the other nipple on the catch can goes back to where the hose was originally connected to? (My oil catch can has two nipples) The other hose seem to be going to the right place. ( nipples after the maf sensor) I do never connected to a nipple on the intake (before the maf) like most people originally did. Did a quick draw to confrim. Thanks again for any input.
Your line to catch can is correct; that hose is conected to those 2 nipples on the side of your UIM; right?
Run from there and over to a nipple after the MAF; preferably the one that is not being used - OR being used as the oil line already. In my case; one of them was running from the back of the oil filler neck (I have another nipple back there)...

isn't the oil catch can just to keep oil from entering your turbo and intercooler? on the updated models the oil lines go to the UIM so there isn't really a need for a catch can like earlier models that routed to the intake tube.
ditch the greddy maf housing. When I did it fixed the problem of rich in boost. Just get a 3.5" OD pipe and replace your greddy maf and that pipe in front of it. drill the 1" hole in the middle of the new pipe and mount your maf there. Get a 45 degree silicone coupler for just after the maf, and whatever is inside the bumper to fit your new 3.5"
Grouch, I am trying to get to your diy, just time hasn't permited me to fabricate the certain piping I need.
Kane, is your piping powdercoated? I would like to do something similar. Please let me know if you did it yourself, if so how did that go. Thanks
The can is used to prevent oil vapors from going back into your engine intake track; regardless of where the stock set up sends it (UIM vs Intake).
You don't want old nasty oil condensation in your intake tract.

Yes; my piping is powdercoated (high temp; the good stuff)
I had it done; but it was all but free from a buddy of mine. I think you would pay very little to get it done even without a hook up <$100.

yeah i guess the biggest thing is finding the adapter flange to mount the MAF on a piece of tubing. it is kind of nice to have those flared edges too though.
I just connected the other end of my catch to a breather. That's how I have it. Why recirculate the oil back through your intake to clog things up!
Also, just found a chrome 3.5" exhaust pipe at pepboys for 20 bucks, it's about a foot long. going to cut into the pipe and make my own CAI following these directions

+1 although i dont see it being very difficult to figure out
Check this out:

Anyone know offhand if the MS3 AEM CAI has the same piping as ours? If so I'm going to get one of these.
