Introducing the GMC Sierra 3500HD Boost Tubes by Banks Power, a top-of-the-line upgrade for your vehicle's performance. Precision-engineered with a 3.5-inch diameter, these mandrel-bent, aluminized steel tubes are designed to increase airflow and power for your Sierra `20-`26 models. Available in an eye-catching red, these boost tubes are not just functional, but they also add a unique style element under the hood.

The Banks Power Boost Tubes are renowned for being the largest available in the market, guaranteeing an improvement in airflow by 26-45% over stock models. This increased airflow is achieved through the use of smooth mandrel bends, which ensure less pressure loss and quicker turbo spool-ups, thereby enhancing your engine's performance and horsepower. Made from high-quality aluminized steel, these tubes are built to last and withstand the high-pressure demands of your GMC vehicle. They also integrate seamlessly with stock Duramax intake components via high-strength, 5-ply silicone hoses. Additionally, the unique billet aluminum cold-side adapters ensure optimal airflow for the L5P engine's specific requirements, maintaining boost pressure with precision-engineered Venturi-like tapers.
