Not sure which 2012 Nissan Armada Air Intake Systems are right for you? We have over 236 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. James G from Lake Zurich, IL said, "I was a bit hesitant about purchasing Airaid since I have used K&N products for years. I previously used only the K&N filter element in my 2008 QX56, but I decided to upgrade on my 2012 Armada to the full CAI. Wow! What a difference. I'm not sure if it added any horsepower, as it's a truck and I'm not out running quarter Mille ET's, but the sound is amazing! I find myself pushing the throttle further, simply to hear the sound the intake makes. Installation was easy (about 1 hour)."
