Review on K&N Cold Air Intake Kit: Boost Horsepower for 2004-2015 Nissan/Infiniti 5.6L V8 (Armada, Titan, QX56) - 77-6012KP by Harry Ashcraft

I installed my intake as soon as it arrived. Installation took about an hour and all you need is a set of allen keys, a 10mm socket, a 10mm open-end wrench, a flathead screwdriver, a Phillips screwdriver and a pair of scissors. What surprised me the most was the change in engine sound after installation, you get that deep, raspy sound that I wish I had when the truck started. I noticed an immediate increase in fuel economy (not much, but 1-3 mpg depending on how I drive) and slightly more power (nothing to write home about, BUT under $300 is worth every penny) . I highly recommend this product. to all those who are thinking about buying an intake for their Nissan 5.6.
