More Air for More Power. Upgrading your 2009-2013 4.8L V8 powered GMC Sierra 1500 to a RedRock 4x4 Cold Air Intake will greatly improve its overall performance. You will see and feel a noticeable increase in rear wheel horsepower and torque just by replacing your Sierra's restrictive stock intake with a RedRock 4x4 high flow filter assembly. Not only will this RedRock 4x4 Intake improve airflow for an increase in power, but it will also add a show winning appearance to the engine bay with its brightly polished aluminum intake tube.

No Tune Required. RedRock 4x4 engineered their Cold Air Intake to improve the performance of your Sierra without the need of reprogramming the computer. By utilizing flow dynamics, this Intake will increase power using the original factory tune. Even though a re-tune is not required for operation, AmericanTrucks recommends a custom tune to reprogram the vehicles computer (ECU) to get the best possible performance from this Cold Air Intake.

Reusable Air Filter. The included high flow air filter effectively filters out power robbing particles with its multi layer design. The specially treated media creates a sticky surface to capture microscopic contaminants before they can enter your Sierra's engine and do harm. Seeing that the filter is reusable there is no need to buy a new filter every few thousand miles. You can just clean the filter, re-oil it, and reinstall - saving yourself money in the long haul.
