Ram Air

I've got my cone filter inside the the fender with no box around it. I want to get a ram air hood. Would it decrease the ram air effect by reversing or decreasin the air flow from the fender?(my filter has a heat shield around it with an opening at the end.)

If you have a heat shield around the fiter, you have cut most of the air from coming into the filter.
Ram air has a hole (with gasket) in the top of the air box. Air is forced in from the hood, or in some cases thur the vent from hoses under the front bumper.
I may be wrong, it's happened before, right guys? But the heat shield goes around the pipe going into the supercharger.

This is the filter I got and the opening which is inside the fender should take in enough air I think:

My question really is wether the air going in from the hood will reduce the air coming in from the fender?

you shouldn't lose pressure that should cause any concern. the thing i would be concern about is the heat shield around the filter.

Do you have a ram air hood?

If not you don't have air coming in from the hood.
