Super Mysterious Vacuum Port

Just wondering if anything is supposed to plug into this vacuum port on the throttle body. Not really all that mysterious lol, sorry. 03 xb9r

Nope, usually they have a cap on them. Or at least mine does.

As Cosworth said, you do want to add a rubber cap. It will keep unfiltered, dirty air from getting sucked in.

If I remember that right it used to go to the charcoal canister for emissions, I pulled all that stuff of my buddies 03 XB9sl. Cosworth is right, just cap it off.

48 state models would have a cap, California models would have emissions hose there
