K&NCold Air Intake Kit: High Performance, Increase Horsepower: Compatible with 2004-2015 Nissan/Infinti (Armada, Titan, QX56) 5.6L V8, 77-6012KP

I have a 2012 Nissan titan, as some a little skeptic, I purchased it and I'm very impressed, gain more power and sounds good the installation was very easy about 1hr, No check engine light, I would recommend it👍

Me gusto mucho , el sonido es intimidante

Fits great, but actually feel it lost power. Going to put the factory setup back on and compare.

So after a bit of research, I decided to give this a chance on my 2012 Armada Platinum.The install took 45 minutes to an hour, with only minimal tools (screwdriver, slip joint pliers, 10mm wrench and an allen wrench). Everything fits great, and looks like it belongs on the vehicle.Immediately after installing I hopped in to give it a try. At anything other than mashing the throttle the sound is barely noticeable. But at WOT it has a throaty rush that sounds amazing!! Instant smile.The throttle response is now almost instantaneous and can chirp the tires before traction control puts an end to it. In addition the Armada seems to coast better, dosen't feel like a parachute is behind me while coasting to a stop.As far as gas mileage goes we will just have to see. I was averaging about 12.8 mpg, I just took a little road trip and it showed on the highway I was getting 16.9. I'll just have to see if there is an improvement.I believe that this is well worth the money. 100% happy with this purchase!

First and most important, it is critical to follow the instructions closely. Second and equally important, the instructions were aweful. Serious 35 pictures of inside the engine bay and 1 liners like put it the bolt as shown - it is a thumbnail sized photo of the whole engine.So I had 3 things I had to rework. 1 - the back most bolt that already had a bolt in it does not get a nut. You realize that when you're a nut short 10 steps later. 2 - does the negative cable go in front or behind of the bracket. 3 - the mass airflow sensor can be installed backwards and the symptoms are truck starts and the immediately stops.But it took an hour or so to install. And when I went out on the test drive - oh my gosh that sound was worth it. I was way down on star ratings when my engine was failing to start, but then 10000000 stars when I drove it. The gains were legitimately noticeable. It revived my old old old truck. And I thought that was enough. It almost always stays at 1-2k rpm. But I went to get on the freeway and stepped on the pedal and it sounds so good at 3k 4k and then superman 5k. I can't remove that smile. So I forgive it being a little tough to install because of the instructions and love it. It helps that I got it 40 dollars off and for July there's a 50 dollar mail in rebate.
