Just put one on the car yesterday and it was a bit different than any other cold air I've put on in the fact that you do have to change a motor mount to a thinner one that comes with the V2 intake. I noticed an improvement all around and definitely no loss in the lowend. Excellent quality and fit. We hadn't sold any to anyone local to check them out so we figured we'd put one on our GSR. Sounds nice too of course.
