A year or more ago I received the P0299 error. I watched a few videos and they removed the innercooler to swap the blow off valve. None of that is at all necessary as I found out today because I finally got around to it.
1. Rotate the white clips 90 degrees and pull the protective cowl out of the way
2. Rotate the hose clip counter clockwise like they show in the YouTube videos
3. Use a short 8 mm socket to undue the first bolt/screw.
4. Undue the wired clip by using a screwdriver to slip under the plug (I spent more time at this than doing anything else) and pull it off
5. Use a longer 8 mm socket to remove both bolt/screws that hold in the blow off valve
6. Insert the new blow off valve
7. Reverse steps
Assuming you are less lame than me, you’ll get the plug off in seconds instead of 7 minutes. Total time should be under 15 minutes.

I am a 20+ year government employee so if I can do it-so can you!

I replaced mine today but the new part (orange) looks different than the OEM part.

Is it just a new version?
2017 expedition.

The replacement worked. If your expedition isn’t feeling as powerful as you think it should this may be the culprit. You could not be building boost and still not throw a code everytime.

I am now pushed back in the seat when flooring it.

Does this valve use a gasket or sealant? Or, does it seal with what looks like an o-ring... the green part showing in the photos? None of the images show a gasket, but I wanted to make sure.

Before you replaced the blow off valve, were you getting oil leaks from the intercooler in that area? My 2015 Exoy has started dripping oil from the area just above the flexible cover with the four white clips. I read another post regarding oil leaks from that area, and it was coming from a bad o-ring on the charge air tube. I have a new BOV coming, and I hope that takes care of the oil leak. If not, the air charge tube is probably next. FYI, I have not drilled a weep hole..... yet.
