Review on 🚀 High Performance K&N Cold Air Intake Kit: Increase Horsepower, Compatible with 2008-2019 Nissan (Frontier, Xterra, Pathfinder) 4.0L V6, Model 63-6014 by Ben Boulanger

Bought 7 months ago. Relatively easy installation. On start up I immediately noticed that it was pulling air through a slit under the hood where it wasn't there before. I can definitely feel the power. I noticed that I was starting to accelerate a little faster and the acceleration became SMOOTH. Keep in mind it's only 15hp, so not a huge improvement. Honestly, the sound is the best. With my window down I can hear air being drawn through the hood when I accelerate. If you mess with it, it absolutely comes alive at 4000rpm, like a switch is flipped and you can hear it running. Looks like a crazy leaf blower! No kidding, it's like a dull groan that makes your hair stand on end. Although it is better if the window is lowered. Overall a good product. Maybe not worth the money to be honest but not much gets done for our trucks so we take what we can get and that's my hobby. The dyno was tested at 230 hp. when raised 3 inches and 32 s. Trust the schedule they give you. The increase in gas mileage made up for my lift and tires, so about 2mpg city. Have 16 about 18 in town now. If I removed the lift and tires I could probably get a 20 with the covers down, which is also a great buy (1-2 mpg city).
