So my car has the grimmspeed 3 port solenoid:
and a Mishimoto induction hose:
On the diagram for the solenoid, it shows port number 1 going into the center input of the induction hose.
What I noticed on my car is that port number 1 is just open to the air, and the center port of the induction hose is just capped off.
So why wouldn't it just be connected? Is there a benefit to it just being open as opposed to venting back into the hose? Should I try connecting it?
Yes, this is not a part that I installed, it came this way. Thanks for your thoughts on this.
