    Here is my first impression of the Injen intake and observations since this is my first time with Injen. I've personally used Stillen Warm Air Intakes on my past 2 Altima's and I must say that I love the deep throaty sound that they produce. I've also used AEM's Cold Air Intake on my 2004 Altima. I decided to go with the Injen this time for a couple of reasons:

    1) I liked the idea of a heat shield

    2) The tech behind the filter material on the Injen intake (dry-weave)

    3) They've got some great R&D on their intakes

    Love the look of the intake. I decided to go with the black intake instead of the polished look. If I could post pictures I would. There is a deeper tone to the intake but the Stillen intake provides more of an animal growl to it. If you're going for sound, pay for the Stillen Intake. Overall, I am happy with my choice of intake.

    Best, economical move for highly improved performance. 2012 Juke loves to SUCK in air, you can hear it clearly sucking it in...

    Added a Rear Sway bar which added fun, fun, fun on a track too, for $180 bucks, much less than a set of tires, the Juke feels like a super low go-kart.....

    Added the Stillen high flow exhaust muffler and this baby breathes sooo much better too, all this improvement for the total cost of roughly $600! VERY reasonable to upgrade the Juke to high performance for a little 4 banger...VERY pleased with Stillen and particularly Stanley Wu for talking me through the upgrades...
