Keep the flame of adventure lit and dominate the dirt with an Airaid performance cold air intake system designed for some Chevrolet Silverado and GMC Sierra 1500 models. This air intake system features a CAD-designed intake tube engineered to accelerate airflow to your engine and reduce restriction, paired with an enclosed air box to help protect the filter and inlet from the heat of the engine bay. This system also includes a washable, reusable oiled SYNTHAFLOW® air filter designed to capture contaminants and provide top-quality engine protection. This simple-to-install, sophisticated system helps maintain proper air-to-fuel ratios, and eliminates the need for recalibration after installation. Just bolt it on and go and enjoy your new horsepower gains. Not legal for sale or use on any pollution controlled vehicle in California.
