K&N 57 Series FIPK Air Intake (50-State Legal) - 57-6012

Very easy install and looks great! I installed it on a 2010 Nissan Titan and was a little disappointed when my MPG's went down by .5 mpg. Noticeable improvement in throttle response. Overall impressed and hoping the gas mileage will go up when I do exhaust.

You have to love the whistle! No seriously, the noise that this intake provides is one of the reasons I always have bought an air intake. I put this on my 2006 Titan and have loved everything about it. The power it has given the truck is noticeable. The gas mileage not so much, but that is probably because I have a heavy foot. I added exhaust and a programmer as well. This is a great product.

Happy with this product. The instructions could've been clearer, but install was pretty straightforward. The intake looks and sounds great! For those interested in power, K&N is one of the few manufacturers that include a dyno map of the power gains. You will notice the overall gain is only about ~10hp at the rear wheels around 5k RPM, but the improvement from idle is much more substantial over stock. The throttle feels much more responsive.

I'm seeing a small increase in gas mileage, and I mean small. When I hit the gas, though, the engine does seem to respond instantly - that's nice. Hopefully my next road trip from CA to MT will show an increase in MPG. I think the most money I'll be saving is in reusing the K&N airfilter. If I see any change, I'll let you guys know.

This was very easy to install and was a great value

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+).

I have had the filter on for about 3 weeks now on my titan love it !!! I don't know much about the gas mileage improvement but can definitely say the responsiveness and sound it makes when you hit the gas is very noticeable, a must have !!!!

Great product, easy installation, well designed and performance is great. Love to hear her breath when you get on the go pedal!!

Easy install, sounds great and definitely feel the difference when flooring it.

Happy with the product, better than i expected. My truck has seen an increase of horsepower and mpgs. Also a deeper roar.

Wow this filter unit was ready easy to install and seems to work really well. I like the subtle sound difference this filter makes and with the increased horsepower, the package is well worth the investment. This unit is a perfect fit in place of the original. I totally recommend K&N air filtration on all air breathing intakes.

This is the second K&N air intake I have put on my vehicles and I would do it again. It improves gas millage as well as engine performance. It improved the millage by 3-4 miles\gallon on my last truck. I'll have to do the calculations for this one. I would definitely recommend this to anyone wanting to improve gas millage or engine power.

As soon as I took off my old intake system and put the K&N intake in my truck I felt the power I highly recommend this intake system to anyone that has a Titan

Deffinately feel the difference with this thing installed and can see the difference when monitored with the Bully Dog performance tuner. Installation with the included directions was a breeze as well.

shipping was fast n free, real easy to install, appearance is awesome, the extra power OMG can't believe the difference,fuel mileage the same if i keep my foot out off it, n the difference in the performance is awesome...
