Don't really feel much of a change at all. Installation was a breeze, 15 minutes maybe. My k&n high flow CAI already gave it the power before getting this and I would've been able to tell if any power change were there but didn't really. I don't know where they got that it gives up to 50 ft-lbs of low end torque. The whistle gets a little annoying but makes it sound almost like it has a turbo. For what it's worth, i wouldn't buy it again. But it's ok I guess.
