The GMC Sierra and the Chevy Silverado have been using the Duramax Diesel 6.6 liter engine for some time now and in terms of towing power there is good reason to do so. The 735 lb-ft. of torque (measured at the flywheel) makes for easy towing and a GVWR of 13,000 lbs. This is a lot of weight to be pulling around. For a hard working truck like this you will need all the power you can muster available at the wheels.

Dyno Chart for the 63-3077 air intake system
K&N Air Intake System for new 2011 to 2014 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD 6.6Ls
The K&N 63-3077 AirCharger® air intake system is designed precisely to make that additional power. This air intake was dyno tested and achieved an estimated gain of 19.3 horsepower and 44.6 lb-ft. of torque at 2420 RPM, all to the wheels. That's a huge increase of power to the wheels, perfect for hauling that big trailer along with you and right in that range of acceleration.
This added power is achieved by allowing additional airflow to the engine. The K&N cotton gauze air filter is designed with this in mind, and when attached to a custom intake tube that has also been optimized for airflow, it results in an increase of horsepower and torque. Between the two, we are able to create the estimated dyno tested power gains shown above. The air filter on this intake, like all K&N intake systems, is oversized for optimized airflow. Additionally, this air filter uses 6 layers of oiled cotton gauze, and a tighter weave of cotton for additional protection for the tighter tolerances and higher stresses of a turbo diesel motor.
Air intake 63-3077 comes with detailed installation instructions that make adding this diesel performance modification very simple. You will only need basic hand tools for the installation. The K&N 63-3077 is designed specifically for the GMC Sierra and the Chevrolet Silverado, and it will not void any factory warranties. This air intake system will not need any further tuning or modification to produce the additional power. This air intake is also backed with K&N's Million Mile Limited Warranty.
