View Full Version : Throttle body size

Can someone tell me the ID of the stock throttle body for the 1.8t and B5 S4? I want to source out a throttle body with a 2.5" (65mm) ID, and I can't seem to find a clear answer whether the B5 S4 is 70mm or 65mm. Thanks!

I heard the early ones are 65mm and the later ones are 70mm...but, I guess thats not a clear answer either
