The K&N 57-6014 Air Intake fits some Nissan Frontier, Nissan Pathfinder, and Nissan Xterra models. See vehicle applications link for details.
The K&N 57-6014 FIPK air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-6014 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the mass air sensor and crank case vent hose. The oversized cone-shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a couple of screwdrivers, pliers, a socket set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Great product. Immediately could hear and feel a difference in how the truck performs. Haven't driven it enough to know how it will affect mpg, but it sounds much better, and low end torque is definitely better. Instructions were easy to follow and it took me a little over an hour to get it installed.

Love the product, 2nd. truck I've installed an FIPK on. Delivery was 3 days later than posted, but I think that was a UPS problem.

Quality product, with easy installation. Mileage increased from 18.3 to 22.7 MPG, and that included 800 miles through the mountains. There's also a very definite increase in horsepower. I would definitely recommend this product.

Experience based on 2013 Nissan Frontier SV 4X4 (4.0L V6) (weight around 5800 pounds) Large increase in throttle response. Mash the gas and you will hit redline very a great roar almost giving a V6 a sound as though a V8. MPG can increase with CAI however, that depends on your acceleration or if running the AC,Heat, etc. According to my OBDII sensor hookup while running the Torque application I am getting 23 MPG highway and potentially higher depending on distance traveled. City MPG averages between 18.5 and nearing 20. I haven't done a great deal of tests but based on some experiences with current outdoor temperatures, etc. and whether the AC or Heat is running as well as acceleration will greatly skew results for MPG increase. Overall a great buy and assists in really beginning to open up the engine and removing restrictions. As a current Nissan employee (mechanic) I would recommend this to anyone.
