The K&N AirCharger 63-6014 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 vehicle’s 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 63-6014 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that mounts onto the inner fender. This allows cooler, denser air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized 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 requiring only pliers, a couple of screwdrivers, a socket set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Welcome added bump in power. I own a 2015 Frontier SV V6 6 speed and it is really alive now after the K&N install. Simple Installation, sweet swishhhhh everytime I step on it. Fun Lively truck.

This intake really works and sounds unreal for the 4.0 v6 under the hood.... above 3k rpm and the monster roors nicely.. def better power across the band and sure gas is better also... Best 300 I've spent in long time.. A must get.

Easy to install. Fits ok but doesn't come all the way up against my hood. Not sure if this will be an issue yet. I'll get more weather-stripping if I need it. Fuel mileage has improved. Power has increased. It gives me extra pulling power up long grades. Sounds GREAT I installed it on a Xterra.

1. So easy to install my teenage daughter could've done it. 2. Very pleased with the increased horsepower,and with that said one needs to be easy on the pedal if you are looking for improved mpg. 3. Very pleased with the increased mpg in my new 2015 Frontier. I went from 10.4 to 13.8 city and 21.0 hwy with cruise set at 5 over speed limit. I did do some experimenting with 70 mph cruising and I could see the average mpg starting to tank and know that if I were to set the cruise at 60 my mpg on the highway would be above 22 mpg.

Great intake as always. I've had three different vehicles with K&N cold air intakes and they do a great job of fitting it in the engine bay. I like the performance boost and I love the way it sounds at high rpm's.
