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.

Product Reviews

 I received my order just a few days after ordering it. Very easy to install, I was pretty nervous about doing it myself because I am in no way mechanically inclined. I do notice a difference in the performance of my Xterra.
Bob Voitl, Colorado Springs Colorado
 The only thing I disliked about my Xterra was the terrible gas mileage. I purchased the K&N Air Charger to help get a little better gas mileage and horsepower gain. It didn't disappoint! I'm getting more miles out of a tank of gas and a noticeable gain in horsepower! I'd recommend this product to anyone!

 My son is a mechanic. It was a straight forward installation and he appreciated that the filter was designed specifically for my truck and was a perfect fit. As for me, I like the improved performance, the improved gas mileage, and of course the sound! Good job K&N!

 Easy to install. Shipping was fast. No problems.

 I found this very helpful on my 12 Nissan Frontier when trailering my boat...there is a definite HP increase at higher RPM's when climbing hills.
