Great Intake for the Xterra!

The quality was very good, The installation was a pain. It was not hard, but there are a lot of bolts and brackets. It went from 15 MPG to 17 MPG with slightly more spirited driving on the 17. I noticed the acceleration is more responsive. That is a win-win in my book!

Noticeable sound difference above 4k RPM. Look for reasons to accelerate just to hear it suck in air. Great buy, especially if you use coupon code.

Good intake but a little pricey

I dont have a dyno. But can feel the response. I actually sink in the seat when accelerating. My tire are now slightly peeling. Overall great engineering.

Good Upgrade

Very happy with the end result, definitely more responsive at medium to higher rpm and the sound is great for an SUV when you open up. I only had one issue with the brackets included for the heat shield, the bottom bracket didn't fit my setup on my 2012. The bolts just simply would not lineup, but the other two brackets keep everything in place just fine. I was able to pre-assemble most of it prior to install and everything took maybe 2 hours total.

Just as promised

More HP and more MPG. Sounds great too.

Great for a minor performance boost

After weeks of researching all the different CAI for my 2011 Nissan Frontier, I found the 57 to be the best in terms of value, ease of installation, performance boost and sound. I wasn't expecting a huge difference in performance, as my research made it clear that CAI are a minor performance enhancer, but I can certainly tell there is some difference in horsepower, especially when towing my pop-up tent trailer. I also like that K&N actually provides metrics for performance gain.
