The K&N 63-6012 Air Intake fits some Infiniti QX56, Nissan Armada, and Nissan Titan models. See vehicle applications link for details.
The K&N AirCharger 63-6012 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 63-6012 air intake comes with a large 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 using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Third application on a Nissan Titan. This time is a 2015 4 x 4 crew cab Pro 4X. Again, another great product courtesy of K&N Filters.
