A intake will not make a magical amount of power. If you're stock you will still have a learn down feature, and make the same power. If you're tuned, your car will benefit from a bit more air, but a retune might be needed to help with the fuel trims.
I vote k&n. Well made, and installs easily. Just make sure the filter itself is installed upside down with the metal rib at 11:00

Magical numbers pulled straight out of the manufacturers a$$. lol

Lots of people had trouble getting the fuel trims right with the filter on the correct way. You can adjust your stft and ltft just by rotating the filter either way. The metal rib up seemed to always be the best option from what people were saying.

With stock airbox/ZZP tube and drop in, power would droop around 5000 and then recover. With the K&N, it just continues to pull smoothly. Picked up 8-10whp on the VD with what I'd consider a moderate ethanol tune (23psi, 20*, .88-.87) that was the same for both, aside from obvious MAF fueling changes.
With your K04+ I'd say there would be a nice gain as well up top.

Stock turbo, very little gain, if any. However, after moving to the K&N with my K04R, there is a pretty noticeable difference. Especially after 5500.
