The Banks boost tube Upgrade Kit offers the market's largest 3.5 - inch boost tubes, delivering more airflow than the stock ones. Its smooth mandrel - bent tubes supply more air to your engine, cut boost pressure loss, and result in a quicker turbo spool and more power.

These boost tubes pair well with the stock Duramax intake components via proprietary high - strength 5 - ply silicone hoses. For 2020+ models, a pair of billet aluminum cold - side adapters are used for the intercooler and throttle body connections. They're designed for the L5P's airflow needs and have a Venturi - like taper inside to keep boost pressure and volumetric flow steady.

Using the Duramax Boost Tube Upgrade Kit is easy. First, make sure your vehicle is turned off and cooled down. Locate the existing boost tubes in your 2020 - 2025 GMC/Chevrolet with a 6.6L Duramax engine. Carefully remove the old tubes and replace them with the ones from this kit, using the provided high - strength 5 - ply silicone hoses to connect with the stock intake components.

When it comes to maintenance, check the silicone hoses regularly for any signs of wear or damage. You can clean the aluminized steel tubes with a mild detergent and a soft cloth. Keep an eye on the turbo spool and power performance, and if you notice any issues, double - check the connections. Also, always follow the vehicle's normal maintenance schedule.
