The only ones I've seen are from Carbnlab motorsport, 034 motorsport, and IE. Since 034's superduper turbo inlet piping was recently released, I haven't seen anyone's vehicle fitted with they yet.
Most of the ones I've seen have been carbnlabs and a couple of them have been IE's.
I just ordered the TTE810 for my s4 this weekend. I am planning on going with 034's SuperDuper inlet as it seems to allow for the highest CFM. Theirs can be purchased with adapters that go to their p34 and x34 intake boxes. Unfortunately, I want an open filter intake so I am waiting for them to release their s34 intake. I hope it comes out soon since I'll likely have my setup ready in a couple of weeks, and summers will likely be here before we know it.
