David Chingby David ChingHere 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.12/31/1969
Russ Huberby Russ HuberBest, 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...12/31/1969
