The K&N 63-6018 intake system replaces the restrictive OEM factory air filter and air intake housing on 2011-2013 QX56, 2014-2017 QX80, 2017 Nissan Armada V8 (5.6L) models and by doing so increases the flow of fresh intake air, which translates into increased horsepower and torque.
Cool, outside intake air first enters the oversized RF-1042 K&N high-flow conical air filter sited within a heat shield, which are both installed in the original air box space. The heat shield protects cooler outside air directed to the engine from horsepower-robbing underhood temperatures.
Much of the horsepower increase can be credited to the XD air filter which is manufactured from multiple layers of oiled extra-fine weave grade cotton filter media originally developed for competitors in the Baja 1000. Oiled cotton has been selected as it offers less resistance than traditional filters.
The extra thick filtering medium also captures microparticles of dirt and dust that could damage your 5.6L V8, to help ensure a long engine life. Each design is verified through K&N’s in-house ISO 5011 compliant filtration testing lab, which ensures that your K&N filter provides high airflow without putting engine protection at risk.
Air is then directed through an aerodynamically-engineered intake tube directly to the throttle body to generate an estimated 10.66 horsepower gain when chassis dynamometer tested on a 2012 Infiniti QX56. The intake tube includes fittings for the OEM mass airflow (MAF) sensor, and crankcase vent hose. Best of all, the K&N 63-6018 AirCharger Intake System can be installed in 90 minutes or less with simple hand tools
And once you’ve installed your K&N cold air intake system you’ve eliminated the need to buy another air filter for the life of your covered Nissan or Infiniti. The only maintenance required is a simple service that you can do by yourself.
