But hte TGV are below the actualy intake manifold, so the manifold itself doesn't do anything but look good (which it does ).BayAreaWRX said:The STI intake mainifold doesnt have the TGV valves. Not proven but supposed to flow a little bit better.
If your intresed i have one for sale. I picked it up from japan and got it of a crashed STI. So it is used but still in good condition. Will let it go for $350.
I do live in Ca, the bay area.
