Very good nice sound to it aswell
From opening the box it was obvious there was going to be much less air resistance, bit sceptic about performance gain claims but I have to say, I noticed when I had my 1.0 Mk 4 mapped, and I noticed this as well. A little more induction noise as well.
Been in a few months now, can easily see the quality of the product. Quick delivery as always, comes with a sticker to easily let service employees know not to throw away
