Does anyone know the correct procedure for removing the plastic intake cover to gain access to the spark plugs?
 
id like to know as well. i wouldn't mind painting them to add some more appeal to the bay. anyone fell like tinkering with it?
 
I have taken mine off. From what I remember you just have to disconnect the 2 or 3 air lines which go to the throttle body. Disconnect tube at the beginning of the intake, then there are I think 3 bolts which hold it in place. Also if you are going to be taking the ECU out it isn't that easy. They use a 5 point torx bit. You can do it with a flat head screw driver though.

On my Mazda 2 (2003 - 2007) you have to nuts on the front-top of the air-filter housing, and then two hidden clips at the bottom-back. The clips are just snap-on-snap-off. Might take a slight-bit of force the first few times.
 
(bit of a necropost, but I didn't want to start an unnecessary new thread.)

Does the plastic intake cover serve any other purpose than air intake? I'm wondering if, after installing an SRI or CAI, the whole thing could be safely removed. I prefer to see the actual valve cover rather than a bunch of plastic when I pop my hood.
 
Actually, it does have a function as mentioned above but it's funny how manufacturers have created these humongous plastic boxes to cover the engine. If I recall correctly, it could be safely eliminated from my M3. But I believe that is the exception since these do seem to have valuable components nowdays.

I know when we bought a vehicle a couple of years ago how proud the salesman seemed to be about his knowledge. He claimed it was a safety device and placed his hands on the plastic box to show how you couldn't get burned. This was on my GMC vehicle which has this huge item bolted on top of the battery. Seems they decided to build a wiring harness on top of the battery. Of course the salesman showed me the jump point since you cannot get cables on the battery. When I asked knowledgeable salesman about the OBDII location his face drooped since he had no idea and then he came up with the answer - that should only be used by a qualified technician.
