Cold Air Intake, Polished Aluminum Tube, 4.8L V8

The RedRock Cold Air Intake is engineered to boost the power and performance of your 1999-2006 4.8L V8 GMC Sierra 1500. The polished aluminum intake tube also adds a show-winning appearance to the engine bay. However, a custom tune is recommended by AmericanTrucks to fully optimize the vehicle's computer (ECU) for maximum performance gains. The included high-flow air filter features a multi-layer design to effectively capture power-robbing particles, and it is reusable, allowing for cleaning, re-oiling, and reinstallation to save money over time. Installation is straightforward and can typically be completed in under an hour, as it is a direct bolt-on replacement with no special tools or modifications needed. All necessary hardware and detailed instructions are included. It's important to note that this RedRock 4x4 Cold Air Intake is not CARB certified and is therefore not legal for use in California or other states that adopt California emission standards. It is not legal for use on pollution-controlled motor vehicles and is not intended for highway use.
