Removing the airbox - tips?

I'm trying to swap my airbox for the removable filter style (picked up the box and filter for $45 off Amazon, prefer staying as stock as possible right now. Car has noted restrictions on the filter checker thinger).

Before having to give up and put the car back together, I was making good progress getting to the filter box. Got the wheel off, liner out, under bumper liner off, got the two bolts in the wheel well out, but it's still stuck and I can't find how to get to that third bolt.

The one tip I found is to take out the headlight, but there seems to be something holding that in as well that I can't see, and the one video I found said to remove the airbox!

Information is slim since everyone wants to slap a cone filter on, but I'd prefer to stay as stock as possible for now.

Any tips? Thanks!

Yup. The dorman tutorial says only 2 bolts. YouTube tutorial for a headlight says take out the airbox. I'm pretty stuck.

To get the headlight out you have to remove the bumper cover. Or with the wheel well liner out you may be able to get between the 2 with a shallow socket and get the bolt out.

The other option is to cut the old box out, you don’t need it anymore so destroy it and get the job done.

Lopping the box out isn't a bad idea... Or just forcing it out after I pull the two bolts out. Would let me get to the third to loosen it up some so I can slide the replacement onto the rubber grommet that holds it in place. Might try that when I've got a full afternoon to make sure I can get the whole job done.

All Duratecs 05-07 have a "lifetime filter". It is inside the driver's side inner fender with a snorkel hose that goes to the windshield. You have to remove the wheel and inner fender liner to access it. There are 2 bolts inside the fender and one in the engine compartment. I can pull one in 20 minutes. Not sure why these guys were having a hard time. Expensive to replace. My solution is to remove the airbox assembly and buy a Universal cone filter. Cut the mass air flow sensor tube and put the filter on it and then put that on the intake hose. This is my Steeda but the principle is the same. Note that the MAF only works in one direction.

This is a replacement that you can change the filter on. https://www.amazon.com/Dorman-258-51.../dp/B009XUXCU8
