The K&N 63-6014 Air Intake fits some Nissan Frontier, Nissan Pathfinder, and Nissan Xterra models. See vehicle applications link for details.
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.

K&N 63-6014 Air Intake Product Reviews

Friday, April 14, 2017 - Part 63-6014
With normal mechanical common sense and reading the directions my installation was a clear cut success and no hickups. The sound is not what I was after but it is nice and clean when it gets on it and the small amount of power it gives makes it just fun and cool. My gas mileage is a touch better and none of my systems but the radio had to be reset. I did not need to get code from dealer or owners manual, it was completely a plug and play project with a sturdy solid outcome. I did this on a 2016 Nissan frontier 4.0L V6. It was just that bit of kick it needed to make it feel like a V8 and sound like one. This was my second intake kit in last 10 years, and both times, I am more than satisfied and enjoy my vehicle more.

If you have a Nissan Frontier with the 4.0, you have to buy this. It is worth every penny. Enough said. Buy one and let it do the talking.

Great product. Easy to install. Fast shipping, even to Hawaii, I was surprised it got here so fast. Noticeable increase in HP. The best is my truck sounds amazing. Thanks K&N your brand definitely lives up to its name.
