Ports on Intake

[Sy370]

Excuse my ignorance, but there are 2 ports on the plennum, on pass. side towards the rear, they are pretty big. I was wondering if anyone know's if they should be blocked off or what. They are behind the "butterflys" if anyone knows what i am talking about. Thanks for your help

If your talking about the back of the upper intake that would be the egr ports and yes they need to be blocked.

I assume you talking about the Throttle Body, the lower port (one on each side) is coolant and is not used in our application.

It may be blocked inside the lower intake. If it doesnt have an exaust leak out the lower hole then no you dont need to.

it doesn't seem to leak anything, the bottom one that is, the top one, i can feel air blowing, nothing for vac. it was blocked, should i keep it block, or does it matter?

I think dgoodhue has it nailed.....you don't need to block them as he said....
