u'd have to ask some1 with a golf.. the location of mine is different and i can only see the top of it not the entire valve.

That's because of something that Forge said somewhere and applies to the diverter valve not the N75.

It looks ok to me gpk.

If I get chance I'll pop the hood on my A3 and confirm it, I would expect some codes to be thrown if it's not plumbed in right and there wasn't any at the nationals.

I'd be more worried about the fire spreading across your rocker cover...

Yep it is definently opposite to stock - I sat there scratching my head trying to figure it out for a little while - You can tell because the 3 little tubes are different lengths (and the long one goes in the same place as the long one on the stock valve)

I'll take a picture of under my engine bay later if you'd like.

so,,the n75 valve has 3 pipe exiting or differnt lengths.the longest should be connected to the tip? or connected to the pipe that is currently connected to the top????

is the race valve different?? I never checked!!! look at this ---->
