What is the main benefit of upgrading the boost tubes?

Upgrading to these larger diameter boost tubes increases the flow area by up to 105% compared to stock. This allows the turbocharger to spool faster and reduces pressure loss, leading to improved engine efficiency and more consistent power delivery.

Do these boost tubes work with aftermarket intercoolers?

Yes, these boost tubes are designed to work with aftermarket intercoolers as long as they use the stock inlet and outlet sizes and locations. The constant 3.5-inch diameter tubing is intended to maximize airflow.

What is the purpose of the spring-loaded constant tension clamps?

The spring-loaded constant tension clamps are designed to maintain a consistent and strong grip on the silicone couplers, even under high boost conditions. This helps prevent leaks and ensures the boots stay securely in place.

Product Details

You get a complete set of left and right side boost tubes with silicone couplers in this Banks Power Boost Tube Upgrade Kit. This kit replaces the stock intercooler tubes on your 2012-2016 Chevy or GMC 2500HD/3500HD with the 6.6L Duramax diesel engine. The larger diameter and smoother bends help the turbocharger spool up faster and improve engine efficiency by reducing pressure loss between the turbo and the intake manifold.

These tubes are made from aluminized steel with a constant 3.5-inch diameter, which is up to 105% larger than the stock piping. This increased flow area helps maintain boost pressure, leading to more consistent power and potentially lower Exhaust Gas Temperatures (EGTs). The powder-coated finish stops before the tube ends, providing a better grip for the heavy-duty silicone couplers and spring-loaded constant tension clamps, which help prevent leaks under high boost.
