Decided to switch out my takeda sri for the stock airbox. Curious what this hose does. Currently have it hooked up to nothing. Thanks for any help, cheers

I bought the car with the SRI so I have no clue where this goes. I was referencing the AEM intake instruction manual to try and put it back in reverse but never shows this hose cause it's always hidden.
Nevermind it's the coolant bypass line. Already have a separate one hooked up, thast why I didn't need to plug those hoses in.
