Thank you! :beer:I know this is kind of a old thread but I have one of those intake manifolds. I bought it back in the late 80's for my 84 GTI, it was a stock manifold modified to accept the Neuspeed bigger throttle body without the need for the adapter and the intake runners were gasket matched. You could tell a difference but it wasn't major it basically revved to redline better was all. Actually last year I sent it to Techtonics Tuning and had it matched to a cylinder head that they were doing some major work to. They cleaned it up and made it flow much better.
