Diagram 05 is awesome, thats what I am running on my R32.
Looks dead stock in the engine bay, also put stock air box in to give it a very stock look.
Didn't have to cut/move or break anything to fit it in and it doesn't even sit that low. I like it because the return pipe to the intake manifold always gets air and it stays cool, so its cool upon entrance to the intake plenum.
Also retained the stock guard lining as well.
Mine sits fairly heigh to be honest, you can see the bottom pipe through the front bar. Its a BLITZ kit, easiest and BEST mod I have ever done.
Nice write up mate, very informative!
