This intake makes a lot of whoosh noises... For real. I'm guessing it has some power gains since I did this with a stage 1 tune as well. Quality is good. The filter is upgraded in the newer ones but it was an issue for me as I had one with a paper filter, I upgraded that with a Spectre Filter from Autozone. the black rubber guard did not fit on mine (i'm guess cause of an earlier make, it's bound to have some issues) but it was a simple washer and bolt fix. The product all around is decent.
