K&N Aircharger Adds 10+ HP to select Infiniti QX56, QX80, and Nissan Armada models

The powder-coated is carefully shaped to seal-off the filter from engine heat

The heat shield isolates the filter from underhood heat, allowing only cold air to flow to the motor

Nissan’s VK56 5.6L V8 engine was introduced in 2003, fitted to the Armada SUV. The engine is not based on the older VH design as used in the Q45, but rather is based on the highly-regarded VQ V6 engine.

The VK56 was designed with the US market in mind, with its larger vehicles and higher required towing capacities and was manufactured in Nissan’s Tennessee plant. The VK56VD is a development of the original VK engine, but with an updated engine block with a taller deck height to allow for a longer 92 mm stroke, while cylinders were bored out to 98 mm. Pistons are of the low-friction molybdenum-coated type.

The architecture of the engine includes a pair aluminum cylinder heads with four valves per cylinder utilizing continuous variable valve lift and timing system (VVEL) on intake and exhaust camshafts. Gasoline delivery is via direct fuel injection.

The VK56DE, now produced in Japan, delivers between 390 and 400 horsepower, based on application, and 401 to 417 lb-ft of torque in its US version. In Japan, the engine is tuned to produce 420 horsepower at the flywheel.

The heat shield is isolated from the engine compartment by automotive grade seals

The intake tube is kept as straight as possible to minimize disruption in incoming airflow

You too have the opportunity to add an estimated 10.66 rear-wheel horsepower to certain Nissan VK56DE 5.6L V8 engines by installing a K&N 63-6018 Aircharger cold air intake kit.

The K&N 63-6018 intake system replaces the restrictive OEM factory air filter and air intake housing on certain Infiniti QX56, Infiniti QX80, and Nissan Armada 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 air filter can be removed for cleaning without the need for disassembling the system

The pleated K&N RF-1042 filter provides additional surface area for increased airflow

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.

At intervals of 100,000 miles, depending on driving conditions, use the K&N 99-5000 recharger kit to clean and refresh your air filter, preparing it for another 100,000 miles of driving. The RF-1042 K&N air filter included in the AirCharger kit is designed to last for the lifetime of your Nissan or Infiniti, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement.

The K&N 63-6018 AirCharger performance intake system is designed for the following vehicles:
