2004.5-2009 Duramax Boost Tube Upgrade Kit (25936)

Fits

This upgraded boost tube by Banks is bigger than the factory pipe and designed to pair perfectly with the stock elbow and intercooler, boosting airflow and turbocharger spool-up time.

Looking for more flow in your truck's boost tube? Look no further! The Banks cold side tube has 60% more flow area than stock tubes and is made from high-quality aluminized steel. The tube mandrel-bent and consitant diameter, allowing for faster turbo spool. With better airflow, you'll experience retention of boost pressure (increased density) and maximum horsepower. Plus, the red powder-coat finish and 4- and 5-ply heavy-duty high-temperature silicone couplers keep everything in place - even under high-boost conditions. These spring-loaded constant tension clamps have an iron grip to prevent leaks and blown boots.
