The regular 12V VR, and 24V VR have slightly bigger snorkels than the ALH cars... There's no screen, and the inlet isn't necked down as small.. Same with the BEW cars, they don't have a snow screen and have an ever so slightly larger snorkel. It's nowhere near as large as the R32 snorkel but it flows more than the factory one.
Once you go front mount, there's really no need for a snorkel anyway. I saw zero difference in IAT with and without on my setup, so I left it off.
edit for part number.. 1J0-129-609-C is the VR6 snorkel for 99-05 US cars and the one I'm referring to..
