Do you mean to remove that whole plastic set up including the air filter covers?
Yes, super easy. There is a connecting piece on the middle top. It has 2 small latches you pull up and then slide it towards the DME (in the US). It pops off. Take off the air filter boxes: A plastic screw and a metal spring clip/wire across it on on both sides. Pull the clips towards the front of the engine bay. Remove the rubber seal running from left to right on then front. It simply pulls off; mind the two round snaps at the end when you place it back. Remove the two plastic trim pieces on either end covering the hood hinges. Take notice how they come out or else you will be solving a puzzle putting back in. (Take a picture). Disconnect the hood switch and smog sensor over the DME. Be careful, plastic may snap. It is a twist off for the smog sensor. Then remove the plastic screws to remove the left and right side filter boxes that funnel the air into the dash. Be careful with the plastic screws; they are fragile. Just a quarter turn. There is also a torx screw mounting to near the strut towers that has to come out. Don't drop them!. You now have the engine fully exposed in the back. You can carefully reach the two oil return hoses with your hands before you pull the plenums off the engine; key to not snapping them off (I have a stash of replacement snaps, just in case). And don't do it in winter or blow some warm air on them first. Perhaps we should do DIY; seems like a big stumbling block for many trying to do this stuff themselves. Next time I will do this, I will take pictures.

It should look like this when you are done. No need to remove the strut braces!

Well having proper lighting is key. I would recommend not to use an extended screw driver to try and go at loosening those hoses around the plenum. Get you a 3/8 DR Ratchet with a 10 inch extension and a number 10 socket, and it's a piece of cake removing those bad boys. If you are using a power drill instead of a ratchet, apply very little torque because you "CAN" strip the heads of those screws.

Also, to gey the little hoses off behind the plenum and at the front under them, I found it to be easiest removing these after I loosened all the throttle body hoses. There is one hose in the back, two hoses on the side towards the back, and one under the front of each plenum.

Last thing, the big hose on the side of the plenum comes off easiest with a good Ole pair off vice grips. To get the one off right behind the big one, you will need a short phillips head. Pictures below of the tools. Hope this helps!!!!!!!!

@rt Yes, I'm going to make that a project the next. I will try and make a video along with it to share the info with everyone else. There doesn't really seem to be any good how to's or DIY on this issue.

The problem with the ratchet is that the socket may get stuck on the screw when you pull off/out. The socket will then fall down in the engine V (or stay on the screw). You will not enjoy that when you are in the process putting everything back on.
