Description

Banks Boost Tubes are the largest tube in the industry at a full mandrel bent 3.5" compared to competitors’ 3” and the stock 2.5" crush-bent tubes. Made of high-quality aluminized steel, Banks Boost Tubes allow for a quicker turbo spool by improving boost pressure retention (increasing air density) between turbo, intercooler, and intake resulting in maximum horsepower.

The Banks Tube Upgrade Kit works with the stock Duramax intake elbow and intercooler by using proprietary high-strength 5-ply silicone couplers and a unique billet aluminum cold-side adapter to further boost airflow.

  • Allow the turbocharger to spool up faster
  • Huge increase in size and flow over stock and competitors (3.5" vs 2.5")
  • Improves airflow
  • Greater cooling capacity
  • Mandrel-bent aluminized steel construction
  • Constant diameter tubing for the best flow
  • 5-ply heavy-duty silicone couplers
  • Spring-loaded constant tension clamps

Flow Improvement

A better flowing intercooler tube and a unique billet intercooler coldside adapter results in less boost pressure loss allowing for more air and fuel to be delivered to your engine. This 87% improvement in airflow is the highest in the industry, resulting in maximizing horsepower, reducing stress on intake components, and improved turbo spool response.
