      Better Horsepower and Torque. By completely replacing the standard factory air box and paper filter element with premium polyethylene tubing and oiled cotton media, the K&N Series 63 AirCharger Cold Air Intake improves your Sierra's engine performance. This cold air intake system provides cool, oxygen-dense air, which results in more combustible fuel and more power for your truck.

      No Tuning Required. The K&N Series 63 AirCharger Cold Air Intake does not need computer re-tuning, so installation is kept simple and efficient. That said, a future recalibration is always recommended if you want to fully maximize the benefits that this cold air intake brings.

      Traps More Contaminants. The K&N Series 63 AirCharger Cold Air Intake uses custom cotton filters with pleats that physically block large amounts of dirt and other impurities. It is covered with a special grade of oil that enables the cotton gauze to keep harmful contaminants locked in and away from your engine.

      Less Waste, More Savings. The K&N Series 63 AirCharger Cold Air Intake is engineered to be washable and reusable, making it an environmentally friendly option to disposable paper filters. As a result, fewer filter waste ends up in landfills.

      Heat Insulated and Free-Flow Design. The kit’s intake tube is manufacture from high-density polyethylene (HDPE). This durable material also has insulation properties to keep the engine bay heat exposure to a minimum. Meanwhile, the tube is rotationally-molded, forming smooth interiors for unrestricted airflow to the engine. All these innovative engineering results in cooler and more efficient air intake for better engine breathability.

      Straightforward Installation. The K&N Series 63 AirCharger Cold Air Intake can be installed with basic hand tools, and there are no extra modifications needed to ensure proper installation.

      Limited Million-Mile/10-Year Warranty. Lasting for 10 years or a Million Miles, this warranty covers any flaws in manufacturing, including materials or workmanship. However, there are exceptions and limitations. To learn more, check out the manufacturer’s website.

      Application. The K&N Series 63 AirCharger Cold Air Intake fits seamlessly in the 2017-2019 6.6L Sierra 2500 HD.
