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 unique to the 2020+ model, a pair of billet aluminum cold-side adapters. These couplers for the intercooler connection and the throttle body openings, are specially made for the airflow requirements on the L5P and feature a venturi-like taper on their inside diameter maintaining boost pressure and volumetric flow. 

  • Allow the turbocharger to spool up faster
  • Huge increase in size and flow over stock and competitors (3.5" vs 2.5")
  • Billet venturi couplers maintain boost pressure
  • 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
  • Bung for a temperature probe
  • Compliments Derringer Tuner, Ram-Air Intake , and Monster Exhaust
