Give me your E-mail address and I have four pictures of a ported S5 manifold that I can send to you. But I don't know how helpful they will be, I tried to publish them to the web, but I couldn't.

No it's not my manifold I just have pictures of it. But you said you just wanted a size reference, and thise should give you one. But to me it doesn't really look that much different, but they will be in your inbox in a moment.

I have an S4, but I think I am about to put an S5 manifold on my car, if you want anothrer HP gain you could do that, I'm not sure how much an S5 intake will give you, but it must be somthing.
