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

Thursday, November 8, 2018 - Part 63-6014
While installation was fairly straight forward, the instructions are less than clear as to which nuts, bolts and washers to use for each step of the process. Aside from that, I can hear the filter sucking in massive amouts of air starting at about 3k RPM and absolutely roaring near 6k RPM. My butt dyno has noticed an increase in responsiveness, it sounds great, but on the negative side my right foot has gotten very heavy as of late.

Great addition to help out with low end power and tourque. At 3200 rpm the truck has a exhaust note which sounds great.

Slight increase in power in my 2012 frontier v6. Good sound at high rpms. Haven't checked fuel mileage yet.
