I have done a lot of searcing for modified stock GSR Intake manifolds and have only really came up with some older stuff. Does anyone have pics of their own manifold or results? What did you do. It looks like the simple idea is to just remove the butterfly plate and bolt back together. Or to grind out everything and have an open plenum. I am currently using a blox mani and am concerned I am getting a coolant leak somehow from it so I am looking to try something else. Any ideas?
