So I have been looking everywhere and can't seem to find this answer. I am looking for the location of the recirculatory valve on the 2025 ST. I have found video and threads about previous models but when I look in those areas I do not see the this valve. did they move it on the 2025 ST? Any help would be great. And I apologize if someone did post about this I just couldn't seem to find it anywhere.
Thanks in advance.

They eliminated those in mid-2021. You don’t have one.

so where would you put the BOV then? and also I know that the 4 cylinder has them that's why I was wondering.

If you wanted to add one to make some noises you would use an aftermarket cold side charge pipe with a BOV flange on it. FenFab was the original. Contact Brett there and ask him what’s up with the new IC connection on the 2025 cars.

yeah I was reading about that. You need to get a OEM 21-24 connector with the rubber end and then you can connect the FenFab pipe. I did take my airbox out and saw where the recirculating valve use to be. There is actually a blank fill where it use to be. Something like this might work

Fenfab cold side charge pipe with your choice of BOV. They also now offers a 25+ OEM Intercooler adapter that will allow you to run aftermarket charge pipes with your OEM Intercooler.

You figure out? I have a 2026 ST that I just picked up. Picked up the charge pipe and bov from cv fab...then to find out...they told me I need to change intercooler to 20-24 plus but the new pipes. Yeesh..

Then I see fenfab has the silicone adapter to use for the 25+ STs that will make it all work without having to change intercooler.

Anyone do this yet to verify? Also, the charge pipe kit came with some kind of relay or something, is that necessary? Seems like whats included makes it over complicated, especially without instructions.

Thanks for the help.

Should work with the adapter from fen fab. Love my HKS on my 25. Brings a smile to everyone's face. No electronic stuff is not necessary.
