very fast shipping. got it in 2 days after purchase. taking out the oem intake and installing the injen one was very simple. took 20 to 30 minutes for me (and it was after work, dark and outside in the driveway) the only thing that gave me a bit of trouble was the rubber piece that goes around the hole in the housing for the filter to make a better seal. other than that it was a breeze. started it up right after install and no check engine lights and idle was smooth. you can hear a very nice sounding throaty noise from the intake from about 3000 rpm to redline. right around 4500 is when you really notice a difference. it pulls so much more now. if you have been back and forth between what intake to get, get this one. i was thinking about this one or the perrin one (which is more expensive) and all the review on the perrin one say it makes no difference and only makes a nice noise. people have dynoed the injen one and its actually made a significant difference in power and torque. one that is noticable everytime you give it the beans. thanks for reading this and buy this intake or else.
