My car is running better but its not 100%. I have plugged this off but was thinking if there is a port there, im assuing there was a hose from somewhere that pluged into it. So I was thinking maybe the port on the opposite end might need plugged as well. Just a thought anyone know?

the hose with teh blue? or teh tiny hose closer in teh pic?

The hose with teh blue stuff goes to your brake booster, the other one goes to the stock boost gauge from your original skyline cluster.. I used this hole for my boost gauge.

No not the brake booster hose with the blue rtv. The nipple that is beside it that isnt plugged of and coming out of the back of the intake? That would just be plugged into a stock boost gauge cluster? Just want to be sure I am on the same page here

yes, the blue goes to the brake booster, be sure to put in a one-way check valve to prevent boost going to your brake booster. the port next to the blue can be use for an aftermarket boost gauge if you are running one.

one way check valve? what would happen with boost going to the booster?

Don't most nissans come with a check valve?

gotcha! Under close inspection, it's behind a clamp of sorts. Damn ninja valve.
