Great Product at a Great Price!
I purchased this for my 2007 Nissan Armada. I consider myself an intermediate level "do it yourself" person and it took me a little over 90 minutes to install. Instructions are good enough to follow, but could be improved. I was able to install this intake by using only the hardware in the box. I noticed an immediate throttle response improvement and significant horsepower gain (11+).
The install was easy and only took about 45 minutes to an hour. At first I thought it was a little loud at WOT but now I really like it. I haven't noticed any significant increase in power but I didn't expect it to begin with. Some say that you might see better gas mileage but I haven't noticed. My foot is always to the floor now.
