This intake didnt make much difference in power but has a good sound at high RPMs was little disappointed in how you can tell they try to make it as cheap as possible on the small things in all the pictures on website you see AEM written on the rubber connecters and when i got it just a few stickers to stick on stuff i would rate it lower than what i was expecting given i have bought the AEM brand before and was very satisfied not as much on this order

Right off the bat felt a sizable power increase at over 4k RPM. Installation was a bit difficult. Had to take off the front left wheel to gain access to the factory airbox. Price is reasonable for the amount of performance gained. Recommend AEM Cold air induction to anyone who wants a power increase.

The instructions were good but not perfect. Don't put the filter on last. Put the filter on the lower pipe and then you can push it upward from below. Also, remove more of the engine cover below and you will have more room to work with especially after removing the lower air duct and resonator. I also did not have to rotate the HID Headlight controller. There was plenty of room to spare without rotating it. Everything else in the install instructions was good and it was a breeze to install. Performance wise, I really notice a better response at all speeds but especially when I gun it between the 4k and 5k rpm range. I did that going up a mountain and I was passing everybody. Outstanding air intake. I would recommend this intake to anybody.
