@mikerob97 any update on your intake manifold project?
Unfortunately, no update. And it may be a while. We are in the process of selling our house, packing and moving. So all car projects are on a temporary hold until we find a new house, complete the move and then set up my garage. Excited for the move, but bummed that I will not be able to work on stuff for while...

Id be surprised if it was bigger enough to make a difference. I just removed the flaps and motor and called it a day. More so did it for reliability over any kind of performance since I know it wouldnt really make any. CKRA swap I would do just cause its easier without having to remove the flaps like the CJAA.

Haven't looked at it super-closely, but how do you remove the flaps off the CJAA intake? Quick/easy? Or "involved"?

About 1hr job if you have the special tool for the intake bolts. Once you get the intake off you remove the valve motor, break each flap off and slide the shaft out. You then should tap the hole and insert a bolt. Also it's an option to use the manifold from the Passat ckra. I did the first method. Ckra manifold is definitely the better way if you want to spend the $.

...special tool for the intake bolts.
You mean the M8 triple-square bolts that fasten the IM to the head? Or are there other ones?
(Gotta think someone diving into dissecting the intake manifold wouldn't view those triple-squares as "special" anymore. ;) )

The special tool has a long extended m8 with a ball head called xzn 8. It allows you to pull the manifold without taking the rail off, so that's the reason for being called "special". Factory tool# T40159. It can be bought on Amazon for $20LINK. You can just take the rail off if you want instead. Manual pic posted of the "special tools" section for anyone needing the info.
