Removal of stock air filter and intake manifold:
I will not say which tools you should use, just prepare your self to have everything around you. Excuse me as I may not have gone in a specific order, but it did the job for me.
Simply lift the radiator to expansion tank return line from the air filter box.
All around.
Lift up the lower plastic holder of the clamps upwards. I think they are total of 3.
The clamps should be free now to pull away from the cover.
Loose the bolt holding the elbow to the air filter box.
You may continue to loose it by your hand.
Loose the torx bolts holding your MAF sensor. Some models need a security torx as I heard but mine didn't.
Other bolt also.
Open the clip holding the coolant return line.
Lift the hose.
Pull the MAF sensor carefully. It might be stuck little as in my case.
Handle the MAF sensor carefully.
Do not damage it, it's an expensive part I heard.
You may put the bolts back to avoid losing them.
Make sure your clamps are set back.
Wiggle the air filter cover.
Your orange OEM filter.
After removing the filter.
Push these hard holders into the arrow direction. One of mine were broken.
Once air box filter is removed.
Now loose the other side of the elbow bolt.
Use some thin hard plastic and insert it between the plastic ring and manifold.

manifold lip----
If you still can't remove it, then it's better to remove the clamp at all like I did.
After you loose the elbow.
There is one hose going into the elbow.
Press the sides to remove it.
Removed.
After you remove the elbow you can look into your manifold.
Found little oil in there, but I guess it's normal.
Loose the chrome bolt holding the oil dipstick pipe.
There is one air valve sitting on the edge of your intake manifold.
Lift it from bottom. You could use something to hammer it up if it's stuck.
Air valve removed.
Now go to the back of your intake manifold and lift the hose up.
Hose is free.
Open the clip holding the electrical wires to your oil dipstick.
Electrical wires free.
Loosen the two bolts holding your intake manifold to the bracket.
Front bolt.
Rear bolt.
Keep the bolts somewhere safe, you will need them later.
There is another air valve underneath the intake manifold.
From another view.
Slide it, move side to side till gets out.
After it pulls out.
Now this connector is difficult to remove, unless you free up the intake manifold.
Remove the throttle bodies clamps or destroy them like I did.
Loose this connector to gain space for other clamps.
Once you remove all clamps, pull your manifold away from the throttle bodies. Wait, don't try to pull it out of engine bay yet.
Now go back to the hose near the alternator and you should be able to disconnect it now.
There is a last hose going to bottom of the intake manifold.
Another view.
It is easier to disconnect from bottom instead of top.
Now you pull out the intake manifold. You will surprised that it's heavy little.
After removing.
You can temporarily hook the MAF cable to a clip.
It's really a good opportunity to clean your throttle bodies and other parts.
In next post I will show you how to prepare and install your CF airbox.
